I bought some heads that are suppose to be gt 40 heads, i talked to a couple of people and they say they are gt 40 cast iron heads but i just wanted to check with you guys, they have gt stamped on the inside of the head next to the springs and on the outside of the head, they have 3 ridges on the end of the head, i heard if it has 4 ridges it is a p head and 3 ridges is a reg. Gt 40 head.
Also i bought some ford racing roller rockers, 1.6 ratio, are all studs universal for the rocker arm or are they diff, i know they make diferent sizes 3/8 and 7/16 which ones should i get( do they come with nuts or do i need to buy them also),they have valve springs on them but i want new ones, what is a good brand to get, i was thinking comp but i figured id ask, thanks for all the help.

Reason: all caps
the rockers should bolt right onto the heads, you don't need studs if they are the right frpp rockers, and should come with a bunch of little screws, shims, tie bars, and little nut lookin things, i have a set, and they fill a walmart bag with all the little bits that came with them..........
if you just have the rockers, no nuts, bolts, shims, or otherstuff, you got the shortstick on that deal
