ARP head bolts

How much should these cost and how important is it to install vs. stock?- Stock LB4 heads cam, boost, some mild upgrades (turbo 57mm, intercooler pump wired direct, adj. fp regulator, walbro pump etc.)

Re: ARP head bolts

I just looked on Summit P/N ARP133-3607 for $82. Is that the right ones? Also do you really have re-torque with VR head gaskets. I haven't re-tourqued a head in 20 years. Thanks Mike

Re: ARP head bolts

So I found (thorugh old posts) that ARP PN-233-3701 is the part to use. Am I correct by assuming that stock bolts do not use washers and ARPs' do? and lastly for the record do you torque, loosen and retorque the bolts more than once. Thanks for any help, I want to drive this thing again, its been sitting for 5 months at least. Mike

Re: ARP head bolts

I think I used the last number you posted but I may have used the 133 number. For stock build you probably could just use the 133-3607. We (SyTy's) generally don't have problem with heads gaskets or lifting the heads.

Yes use the washer, I used ARP lube on the threads as well.

Re: ARP head bolts

yes, you have to use the washers, cause the ARP head bolts have radius'd bottom flanges. and like Dave said use the lube also

also, get some of the waterproof liquid gasket to put on the bottoms of the bolts, since 4.3 (& SBC style) heads are notorious for the headbolt threads being tapped into water jackets. :2cents:

Re: ARP head bolts

You can also save money and use the 350 sets, you will have some extra bolts. but the kits used to be cheaper than the v6 ones.

My prices:

For SBC:
High Performance (Hex) - 134-3601 - $70 set
Pro Series (Hex) - 234-3701 - $180 set

For 4.3L
High Performance (Hex) - 133-3607 - $80 set
Pro Series (Hex) - 233-3701 - $140 set

I only keep the SBC in stock but can order the 4.3 sets from ARP.

Re: ARP head bolts

I was looking through old threads trying to figure out what bolts to use. When I called Summit they told me to use 233-3701 bolts so I ordered them. Now looking it looks like I could have used cheaper ones. The summit description said 133 are for 18 degree heads. Is that what our heads are? Are the Pro Series any better on stock, should I send them back? I also bought main studs, but they were listed for 4 bolt mains they could not find 2 bolt kits, and rod bolts.Is there anything else maybe flywheel?

Re: ARP head bolts

I connected ARP,they insist that I need the 233-3701. Do you think they just don't know our application and are playing it safe.

the 3701 will work its suppose to be a stronger bolt that the 3601. For the price they should be.

Re: ARP head bolts

Are the bolts the same length and diameter as the other set, just different manufacturing and metal. It is hard to spend $150 when I can get new VR bolts for $12. $80 isn't so bad.

The 134-3601 is a SBC set. It has the same size and length bolts as the 4.3 set. You get all the bolts you need plus a few extra. Because the SBC heads take more bolts. And because millions of SBC heads were made. The price is cheaper than the 4.3 set with the same size bolts. ARP makes good bolts.

I wasn't worried about head bolts. I bought a set of stock type on ebay for around $25 and haven't had any problems yet.

Re: ARP head bolts

My next question is about main studs. Again summit said that I had 4 bolt mains, and I said I didn't. I bought a 4 bolt main stud kit 233-5602 figuring I could use 1/2 the bolts. will this work.
