I'm dumping my 350 for a 383, and I had to cut off the outter 4 intake manifold bolts, cause they were stuck. They are torx head cap screws. I can't find the torx bolts anywhere, and when I contacted Summit, they talked to ARP and ARP said that I could use the usual small block chevy intake manifold bolts. Does anyone out there have intake manifold bolts other than the torx head screws?

Umm... the ARPs that I used were 6 pt hex headed bolts. That is the standard ARP intake bolt.

I thnk it will be harder to find torx headed bolts if anything else.
Just buy an ARP intake bolt kit. You could use pretty much any kind of intake bolt you want.
