Does anyone know what size studs and roller rockers i need for SVO gt 40 aluminum heads? i was wonder what my options are i just dont know what size stud i need..
no guideplates its a pedestal mount head, go with whatever rockers you want really, just dont hit the valves on the pistons.. basically those are factory heads just bigger ports and aluminum, so every screw goes back together like a stock E7..
yes they are 5/16's, however the head bolts are 7/16, lol..
SVO aluminum X, Y and Z heads have a 1/2" hole to fit 351W blocks.
So, to install on a stock 302W block you need to buy the 7/16" head bolt or head stud kit with the spacers that fill the gap of the larger 1/2" hole.
