Had the exhaust ports smoothed up and blasted. Just got them back today.

how are you going to ensure that the valves are sealing perfectly when you reassemble the heads?

Everything is brand new, and they protected the seats.

But you can also just lap the valves, and check the seal with the die.

Im just curious since my heads came dissassembled and I just threw them together. No lap or anything. There was a valve job and whatnot, and told that they were checked for seal but i have my doubts

Now if I really had no idea what was done I would take them apart and check them and lap them in.
