i have a set of 200cc aluminum Pro Topline (now RHS) cylinder heads on my small block chevy, and i have a broken rocker stud. these heads are box-stock as assembled by Pro Topline. i need to know what size studs to buy, the heads are set up for a hyd flat tappet cam. any help is appreciated. i will be going to the speed shop tomorrow to get some ARP rocker studs. thanks,
tom yancy.

I'm guessing just standard 3/8" studs for SBC?

thats what i was thinking as well. but i see they make 7/16 studs and 7/16 rockers for sbc, so that put some doubt in my mind. i called comp cams, but did not have time to stay on hold all day, since i'm at work right now. i could get off my ass and check them later, just figured someone here would know. thanks for the reply.

True, but most aftermarket SBC heads come with 3/8" standard, 7/16" being optional. If the heads were originally assembled with springs for a hydraulic cam, they're likely 3/8".

I agree on the 3/8. You dont see too much 7/16 till you get into the heavy hitters. You could probably just google your part number of the head and find out.

thanks for the info guys. unfortunately, the speed shop doesn't have any 3/8 studs so i guess i will have to do mail order.
