Does anyone know the thread size and length of the header bolts for stock heads. Im swapping from shortty headers to LT's and want to replace all the bolts.

Will these work? http://store.summitracing.com/partd...888324+4294908395+4294908331+115&autoview=sku

Those are .750 in, I guess they will be too short?

Yeah, you wont have to many threads caught with the 3/4" bolts. Just a word of advice, if you're going to be running headers get some good copper header gaskets and some Stage 8 locking header bolts. They're both worth there weight in gold IMO.

What pitch with the locking bolts? I have E7 heads, and need to buy locking ones. I see that summit sells ones that are .75 and 1 inch. Should I go for the one inch long bolts?
