I'm getting ready to pull my heads off, but I stripped out one of the exhaust cam sprocket allen head bolts. I'm obviously going to buy new bolts and was wondering if I can go with the older style regular bolt instead of the allen head. Is there a height difference between the head of the bolts and will it fit underneath the timing cover? I don't think I can fit a regular bolt in the intake cam sprocket(AVCS).
My car is really fast in reverse
