In my ongoing project of replacing injectors, I've noticed that most of these torx headed bolts are all chewed up (mostly done by previous owners). Does ARP or some one make a good bolt kit? I need one for the runners and one for the fuel lines. If anyone has any part numbers or anything, I'd be stoked TIA

 

I used allen head bolts from Alloy Bolts they seem to be good quality stainless steel bought on ebay for $20. They come in marked bags and fit runners, TB, top plate, stat hsg, and throttle bracket, here's an auction for a set for a TPI from a company called bolt locker

Just got a set of them myself. They look to be of good quality, now I need matching intake bolts too.

 

What are the different lengths for the runner bolts? PLEASE:hail:

 

That's EXACTLY what I need! 'Cept I don't wanna deal with the ebay thing, and their web page lacks the part number for the TPI bolt kits. Does anyone have the PN or am I just gonna hafta call them during norma business hours? I know, I'm an impatient a$$

 

Just roll to your local hardware store and go to the fasteners section and get some 8mm (i think with a 1.5 thread pitch) allen head bolts and get grade-8 ones if you can. Bring your old ones to find the approx. length. The holes are tapped into the plenum pretty deep so it should be fine if you're in the ballpark (preferably shorter than longer). Its a lot cheaper and less of a hassle than trying to find these kits on ebay and so fourth.

 

I bought a stainless buttonhead kit for my car. I think it sucks. It looks nice, but the stainless is soft. I've already managed to strip the head on a few of them.

 

Short bolts - m8 x 1.25 x 30mm

medium bolts (under plenum to runner) m8 x 1.25 x 40mm

Long runner bolts - m8 x 1.25 x 55mm

I used Hex Socket Caps in stainless. They hold up better than the button heads, and IMO look as good, if not better.
