Yes it can.. But why?? What sort of cam profile and rpm do you expect to run??
Pedestal works fine up to 550 valve lift and I doubt the P heads would flow much over that much lift ???? The Yella Terra stealth pedestal roller rockers are quite strong...

i have stud mounts on my p heads,but u can't buy guides to suit these heads,so we had to cut guides in half set up the geometry of the heads weld them together then strip the motor and wash it just in case something entered the motor from the welding.

Yep, what EBXR8380 said.

What sort of cam profile, valvespring pressure, and rpm are you going to see? I reckon 90% of windsor setups based on std GT40 type heads, and hydraulic roller cams would not stress the valvetrain enough to warrant the upgrade.

The YT stealth rockers are a pretty solid setup...

I was just curious. I know next to nothing about roller rocker mounting and such.
That's why I made the other thread about trying to get my V8 bits together.

Used 7/16 studs on e7s and was able to use chev guide plates with a small amount of grinding of one of the fingers, all holes & pushrods lined up. But thats if e7s and gt40p are the same.
