What needed touched up on the heads if they were in spec? Did you have porting done or was this from the engine/bearings going south. Good on ya with the engine though. If only more people in this world would take ownership in anything they do.
By the way, how much HP is the whipple motors in your beak boat cranking out. Bet that thing flys!

if my thread shows anything that would be that not many claims of issues with aftermarket heads.i will add that in my opinion company,s like dart and afr might know a thing or two about producing a good cylinder head.can a bad one slip through the cracks once in a while,i would say yes.just like a new car,something can go wrong.

Sent my heads in to get milled as well as the exhaust valves and springs changed...
They are 2008 vintage / never ran. They were not ordered necessarily for a marine application.. Just their basic off the shelf head.
The intake & exhaust valve guide clearances were BOTH .0018 out of the box...

Raylar head, measured one intake and exhaust guide. .0015" intake, .0017" exhaust out of the box. Valves were not installed dry, installed height was right on.
Time to bolt them on and

so can any one recommend a GOOD head/engine builder before I waste money on "off the shelf junk" I don't trust anyone local to build a good performance MARINE engine.
Hell I'd wrap a new set of heads in my wifes wedding dress and seat belt one into the passenger seat the other in my kids car seat, then drive them 7-8 hours to chicago or detroit to bring them to a good reputable builder.
I was leaning towards dart or edlebrock heads but after reading through this I'm definatley going to look at unassembled heads and bring bare heads to a good shop to have them put the "non assembly line"
finishing touches on them.
