Did you check how worn or out of round the cylinders were before assembling everything?
Yes. I was lucky, it was still within spec.

I'd say, not good. You do realize that the heads are now .005" UNDER the minimum thickness? How's your valve recession? That has to be in spec too. This is why I had to install decomp pistons myself. The "machininst" that I took my heads to took .010" off of one and .012 off of the other head. The difference between the maximum and minimum heights is the .010" that was removed. I'd recommend the decomp pistons. Before you install a Typ4 cam, check the valve to piston clearances too. You may not have enough clearance to run Russ's cam. In fact, be sure to check the valve to piston clearance if you're installing a stock cam too. As for your question at the end, if you take the heads to another machinist, you'll have to pay for the work again. On the other hand, the machinist that worked on your heads and "has dealt with IDIs before" has already caused you headaches by not finishing your heads within the specs. Your call. Just a FYI, if you do check your valve to piston clearances (and you really should) Fel-Pro head gaskets are .010" thicker than Victor-Reinz head gaskets. This is both compressed and uncompressed. It may make a difference in final engine assembly.I measured the deck to deck height and got 3.790". Spec is 3.795" to 3.805". Not bad.
Or worse, not recessed enough.Risk of being too recessed?
Got my heads back from the machine shop today. There were some minor surface irregularities pre machine work, so I told them to take the minimum amount off the surface. They ended up taking 10 thousandths off. Wasn't super happy about it.

This is why I write "machinist" instead of machinist. One knows what he/she is doing while the other just thinks it.Ten thousandths is more than I would call "minimum to clean up deck imprefections".
I have a set of mahle gaskets laying around. Any info on those compared to the thickness of felpros?Or worse, not recessed enough.
