Header trouble.

The studs say they are for a 3/8 thread, the heads on the 360 are 5/16. Are you sure these work with the la heads? Just curious because I was looking for a set of studs.

You are right about the 5/16, on a small block. Never thought much about it ad says also fits small block, all I run right now is big block til just recent
I was pointing out about using studs for ease of removing and installing

I tried to find 5/16 studs for you. Below is all i find listed (3/8") says for small block, guess, that is incorrect
