Overhead cams are always measured at the valve.  In addition, the low rocker ratio generally demands a lot more duration to fill the cylinders.  I usually run anywhere from 12-15 degrees more on an FE SOHC head than I do with my wedge FE heads.

The PA bells that I've used were cast aluminum I think.  The Quicktime bells are steel.

RM-9056 would be FE to C4.

They are discontinued, I just checked.

Great, that's 33. 

I'd get the rest and keep them, but I don't anticipate them being a big seller.

Garifo needs 12, so we may get there. 

Bearings fit perfect.  Been trying to shop pricing across various shops.  Looks like the best I'm gonna be able to do is $21 per individual bearing.  Not sure if that's worth it to anyone but I'll need to order 50 to get it at that price.

If it helps, don't twist.  Twisting will give you a false sense.

Loosen the adjuster up so that you do have lash, then you can move the pushrod axially back and forth while you're tightening the adjuster and you can feel when the lash is taken out.  When you have zero lash, then set your preload.

Couples of notes here:

1.  You can get pretty close as long as the cylinders are on the same center as the gasket.  I've ran a lot of 4.375" engines with 4.400" gaskets.

2.  I would pick the head gasket last.  Tolerances can stack up against you and even though you plan for (for example) a 1.325" compression height, 10.150" deck height, and a 6.700" rod with a 4.250" stroke, you can get a stray .001" here and there.

Looking for standard bore.  Can arrange freight if you're not local.
