Re: WHOA, McCoy ported heads have putty in the ports chipping!!! ---

Jerry just emailed me and said if I send the head back to him, they will correct the problem for free....that is very respectable. I wonder if he is just going to use the same stuff again though, these heads only have 5k miles on them. ---

Re: WHOA, McCoy ported heads have putty in the ports chipping!!! ---

i do machine work, in texas city texas and have done some personal port and polish work and have done some for friends, and have never seen this epoxy crap, in my opinion all this crap with the heat and the fuel would, in time just come apart, if it was done right from the start and with plenty of patience it could have been done right, i just don't understand the cost of some of these jobs that cost so much!!!!! sorry about the boat anchors and hopfully you can find a better machine shop!!!!!!!!!

I was going to do vortecs but didnt want to spend $2500 on the setup , and didnt have a place to leave my truck while the heads/manifolds were off of it to be modded/ported. The l35's seemed like a perfect solution. These flow 250 intake and 190 exhaust which rival unported vortecs.

I don't know how you came up with that dollar figure. You can do a set of vortec's for like $500-$600 to have a used set modded and maybe $700-$800 if want all new. Unless you want some that flow closer to those numbers you have posted, but again I can't imagine it costing that much to be in that flow range.

As for down time it should be minimal if get all the parts there and do the swap. You can buy your intake modded and then send yours back for a credit so you don't have to wait to have it done.

Either way it sounds like they're going to fix it for you, hopefully it does get fixed.

If you use a stock vortec's that are complete with valves (and this also assume your not using a stock or mild cam) You can get away with a reasonbly cheap Vortec upgrade.

$200 or less shipped (remember iron are heavy) for stock Vortec heads
$75 to drill them
$300-450 for a modified intake.
$150 for top end intake/head gaskets

You may also want to port match intake/heads mismatch as well.

It get more expensive when you rebuild the heads, new valves/springs/etc, larger valve seats for bigger valves, rocker roller arms & rockers studs/re tapping, and fully porting them..

Re: WHOA, McCoy ported heads have putty in the ports chipping!!! ---

Dave, I completely agree with you, but it's still hard me to imagine it would cost another $1,500-$2,000 just to have that stuff done. I'm going to go do some more research....

EDIT: upon research you can get all the parts for about $650 ish, depending. So unless all the machine work is $1,000 I still think $2,500 is high.

Yeah RPM has their vortec cylinder head package for $2,600, but you don't need that much stuff on a stock motor.

Re: WHOA, McCoy ported heads have putty in the ports chipping!!! ---

I believe the only way to fix your heads is by installing metal sleeves for your valve guides.

Epoxy is OK for Racing, but not for a daily driver that you do not intend to pull apart your engine to freshen things up.
Sounds like somebody got too crazy w/a porting tool. That area(the pushrod area) where they ground all that material away, ,,,(& made a hole),,it really does not kill your airflow if you left it there w/minimal grinding.

Normally,,,sometimes,,,,not all the time,,,, this a sort of a common practice on aluminum heads (Max effort comp porting) install pushrod guide tubes after you have ported through a wall in your intake port.

Re: WHOA, McCoy ported heads have putty in the ports chipping!!! ---

did you actually flow the L35 heads or were you told they went 250/190? @ what lift?

I'm with Mike, I'd get the flow validated someplace locally before I shipped them off to have them fixed. It might not be worth the trouble.

I've seen quite a few heads with Moroso epoxy, but only in a race environment. I can't imagine selling anyone a set of heads with putty in them.

An oops while porting does happen from time to time, but it's the porter's fault, not the customer. The only exception to this would be if a customer brought in a set of screwed-up-port-job heads, and you used the putty to make the short side turn better, etc.

Later,

Re: WHOA, McCoy ported heads have putty in the ports chipping!!! ---

Those are the flow numbers JERRY told me, hehe. I am hesitant of sending them back , because I am not sure if they will be fixed right when I get them back .... I really just want heads without putty, lol. Oh well ---

Re: WHOA, McCoy ported heads have putty in the ports chipping!!! ---

Fellas it's like everything else in life, the epoxy is ok if it's done correctly, with correct materials and prep. Simular to a paint job, it's all about quaility materials and application. Read that whole thead posted a page back, several racing seasons with Alky is a life time for a DD on gas. I have L-35's with Z-Spar Epoxy on my roots blown 4.3 DD truck and. Been on there 5 years / 41,799 miles, flow 258 cfm In. & 218 cfm Ex.@ .550 lift with no problems, 6 years on one of my Harley's. We use the same stuff on any of our customers applications that need it, race or DD with no problem in 7 years and that includes exhaust port, air cooled and Harley engines also. But I will admit that exhaust applications only last a year or two. Still real good if you think about it though.

Are you getting your heads flow tested @ my friends shop?
I saw some of the valves, pretty bad shape.

Re: WHOA, McCoy ported heads have putty in the ports chipping!!! ---

Yea, Dave's got them and that set was from Mccoy's "porter" also ........ they are cracked too and the port work is well, just not worth near what was charged! In quaility or flow. Won't even get close to a decent ported set of L-35's!

Re: WHOA, McCoy ported heads have putty in the ports chipping!!! ---

I am past the putty thing, now I am not sure if I want to send them back....and wait MONTHS to get them back, and risk them being cracked during shipping; OR just have my mechanic reputty them for $5 before I get the rebuild done?! (probably the latter because shipping will be close to $50 there and back)---

If you need New Vortec heads I believe Mike has them.

Naw, I dont want to do the vortec route ... these were l-35's. I was going for the "bolt on" effect, lol ---

Re: WHOA, McCoy ported heads have putty in the ports chipping!!! ---

maybe you can ask mccoy to refund your money as there is no gurantee you will get anything better than what you have now. keep in mind if you paid by credit card ...they offer you buyer protection from stuff like this... just a thought.
