I appreciate that. Rubbing: No thanks.
(Especially not on a thin tube pressed in)

My block seems good (Although I've only checked one cylinder), but it's tight to the tube pressed into the head.

The Edelbrock heads seem like a costly change of plans, but after seeing them up close, I see why Dwayne and Chuck both steered me that way.
