Including valves, springs, and anything else? And have the heads been ported, messed with? migh not be worth much if they have been ported incorrectly....
And, why would a crack in a head cause oil pressure issues? hmmm...
I find the oil pressure remark odd, too. I think it’s unrelated. Like I said, the guy seems like he isn’t very knowledgeable. Didn’t know the difference btw B and RB.
