no too bad, sucks if he wants you to take the head off and bring it in.
I dunno, i got port matching on my intakes and to the heads, I also got some mild porting done on my holleys, all for $800 friend prices
he's probably gonna do a shake and bake to clean them off, check for cracks, put in new seals, check spring rates, grind the valves and seats, and maybe do all of the seals
and of course machine the face of the head
you could get it for cheaper, but if he's good, pay extra, you don't want to go back in 1,500 miles because he cinched on quality guides
jsut my opinion
