Default Would YOU have these heads reserfaced ?
I have beautiful set of PRC 227cc heads that I bought from a follow forum member on here that were bolted to a LQ 9 that I also bought from him.

I bought new Cometic .040" gaskets (the same ones that he used).

Should I bother taking all the valves out of the heads and having them resurfaced at the machine shop or should I just bolt them on?

What would you do if you were me?

Spray the Cometics with Copper sealant. Clean the heads surface well.

I always have aluminum heads lightly surfaced if they are removed. Period.

$40-50 = piece of mind
