Guide plates
Are the guide plates for the Ford SCJ heads the same as P-51 heads?
Thanks Tore

Re: Guide plates
I don't know if they are exactly the same but, guideplates for an FRPP SCJ head work on a P-51.
Re: Guide plates
Tore,
I have two sets of P-51 heads here right now. One set has shaft mounted rockers on it, thus no guideplates. The other set has stud mounted rockers on it, along with guideplates. Those guideplates are stamped; "Kaase P-51". However, just as Randy said, they are essentially the same as the SCJ guideplates and yes the SCJ guideplates will work.
As a side note, the engine builder should check his pushrod to pushrod hole clearance carefully. The pushrod holes may need to be "finessed" down at the bottom towards the deck surface. Especially the exhaust pushrod holes.

Is this for P-51 heads in particular?

Ahh, OK I see that now. Thanks. Hadn't heard of the problem either way.

This is for the P-51 heads in particular. HOWEVER, the set that I am seeing some wear on, is the set that has a set of T&D shaft mounted rocker arms on it. That being the case, I strongly suspect that the pushrods rubbing on the pushrod holes was possibly "induced" by the T&D shaft mounted rockers and their pushrod to pushrod hole alignment.
Guys just a FYI, that regardlessof the brand of cylinder head, Edelbrock, TFS, Ford or whatever,,,,,the engine builder should always check for pushrod clearance with the pushrod holes, AND check it all the way through it's travel, from the valve being closed to open, because it will change during the course of it's travel.
