Regarding the guide plates, once their alignment is set up, they should be tack-welded together (see pic where they "tab" into one another).

Those look like the Isky guide plates. Look CLOSE at full valve lift that the slot is deep enough for the pushrod not to hit the bottom of the guide plate. My RAIV heads with 3'8 pushrods would not work with them for that reason even just using a 1.6 rocker. In fact they hit I think even with no lift.

Good point Skip

I had to clearance the back of the slot with the Iskey adjustable guideplates to fit a 3/8" pushrod. When doing first assembly on a new valvetrain check all clearances to everything moving over several rotations., ant binding, pushrod clearance, rocker slot, retainer clearance, guideplate clearance / alignment etc etc

It may turn over by hand OK with minor issues but zing it to 7k and see what happens !!!

One of the little angle neck mirrors and a flashlight or even a non coated paper clip can be usefull

I recomend only using the SS Roller Rockers on Solid Roller Cams. John Ageles runs PRW's. He did THE EXACT same thing with his Aluminums. Changed to the PRW SS Rockers and is still running them today. But John is running SICK valve spring pressure. Up in the 450 lbs area CLOSED!!

I only Recomend the PRW Stainless Steel Rockers on Solid Roller Cams. The spring pressure of a Solid Roller is just to much for the Aluminums. But of course this is only my experience and opinion.
