I thought the two heads had the same valve angles, but slightly different rocker arm stud locations?

Not EXACTLY the same but, close enough to work OK.

If the guides plates don't line up properly, always be willing to cut them in half, align everything, and then tig weld them back together. That means all types of heads, such as Blue Thunder, SCJ, Edelbrock, P-51 or any of them.

Hope this helps,

Charlie

I have cut and welded BT's & P51's because I wasn't happy with the alignment.
I've since gone to shaft rockers.

If the stud girdles are different then the guides should be as well. My SCJ guides were way off. I hear that the P-51 guides are better fitting on P-51 heads.

The stud girdles are different because the intake studs are at a different angle. The base of the stud is in the same location as those on a Ford Racing SCJ head.

That would make the guide plates head specific too, right? Or am I over thinking it?

The guide-plate is LOCATED at the BASE of the stud. They would have a slightly different "twist" but, will conform to the correct angle when the stud is torqued.
