I bought a set of Holley SysteMAX heads and I found a set of 1.6 rockers for pretty cheap. They're bolt down with 3/8 studs. My question is will these fit my heads? I know I need bolt down ones but I'm not sure if I need 3/8 or 7/16 and the heads won't be here until next week so I won't be able to measure until then. Thanks.
