summit lists stock configuration and gt40 head configuration...what's the difference besides $40??

would like to order a set to replace the stockers

sorry i have P heads incase anyone missed it :bigthumbsup

Not sure about the P heads, but my GT40's require 1/2 bolts or studs just like a 351 head would. I believe the 302 heads would have 7/16 bolts-

it lists both as being 7/16 just dont wanna order the wrong ones and have to wait even longer:yup:
