Stage 8 .750" bolts okay to use with Percy's gasket???

I remember reading that somebody thought that the stage 8 bolts were too short to use with percy's dead-soft gasket... I like the fact that the stage 8's have the allen screw. I'm thinking about getting ARP 1" long 3/8 hex head bolts but I will hold off if the stage 8's will work.

I need a quick answer, are stage 8 bolts okay to use with Percy's dead soft aluminum gaskets (thickness wise).

I have Percy's and Stage 8s, but mine are 1" long.
I think you'll be ok with the 3/4 ones but it will be close...

Do they make 1" stage 8's??? How close will I be cutting it. I don't want any more freaking exhaust leaks. I'm absolutely sick of it.

Get nothing less than 1", 1 1/4' will probably work better. You have to remember the header flange is 3/8".

I think the SLP headers are 1/4 inch flange. The bolt locations are so ****ty I need the allen aspect of the stage 8's... I'm not paying 40 bucks for some stupid bolts that cost 2 cents a piece. If I get any they will be the 1 inch black oxide ARP's.

The black oxides will start rusting, get the stainless steel.

They sure do make 1" long ones.

Scroll down to the bottom of the page.

That's what I have.

I didn't try 3/4s myself, but I've read someone saying that they did.

I have percy's with 3/4" stage 8 bolts. They were a PITA to install but i got it done. You can only get the bolts to barely catch the threads so you have to snug them up one at a time constantly working the header down evenly so you don't put to much stress on one bolt. If i would of thought ahead about how thick the gaskets were i would of gotten 1" bolts.

I think I may just use the stage 8's I have now and then when I end up doing an engine/heads in the future, replace everything with ARP's including the header bolts.
