3/4 INCH BOLTS ARE FOR STOCK CAST HEADS...
1 INCH BLOTS ARE FOR ALUM. HEADS....
I RECOMMEND STAGE 8 LOCKING BOLTS....
NEVER HAVE TO TIGHTEN.....
THE CHEAP PAPER GASKETS...LIKE TO STICK TO THE HEADS AND MANIFOLDS....
I SPENT MORE TIME TRYING TO SCRAPE THAT JUNK OFF...
BUY SOME GOOD ALUM./COPPER GASKETS..
OR USE THE STOCK GASKETS....BUT PUT THE METAL ON THE MANIFOLD SIDE....
