Vortec heads conversion?

[syclone rider]

I mean how hard is it to convert to the vortec heads using the stock lower intake?I have read the tyclones website about the conversion but he gets a little confusing.Can it be done without test fitting them on the truck freakin five times?My heads are at the head shop right now ready to go to the port shop and they are going to do the conversion pretty much. What kind and sizes of gaskets do i need ?Thanks for any input.

I think Tooky did a write up on it. Do a search for Vortec conversion by author Tooky. You may even be able to find it at powertuneplus.com

Jackets?

The Vortec conversion to me is something I would only do if you are going to mod the truck well. We were going to do it on the wifes Ty but decided it really wouldn't be worth it.

I would get a solid quote form someone. There was a company here in CO that is longer in business that was doing the whole conversion for 3-500. My machine shop said they couldn't give me a # because it is a time thing. Well you would think experience would tell you how long it takes to drill and tap a freakin hole:roll: I said no thanks.

A good con to Vortec heads is that there are very few threads on some of the intake bolts. You can avoid a mess if you install everything right the first time. I wrapped my bolts with teflon then put a good amount of The Right Stuff on that. Let dry for a day or so.

Instead of having to get the intake modded I would just install some ported L35 heads. It's a direct port on.:2cents:

RPM has the gaskets. I had a professional welder friend do the manifold, free. I'd have to look up the exact cost but I think my machine shop charged 100 for machining the manifold and, I think, 250 for mockup, drilling, tapping and port matching. Very happy with the setup.

Where are you located? There's a few of us guys in GA. Best to get a machinist who does specialty parts and has maybe done this before.
