Few years ago I put some diffrent heads on my engine. I did some mild port/polish work to them, had a 3 angle valve job, and also had them shaved a bit. If I remember correctly, I believe he said he shaved about .020 off them.
When I installed the intake, I just about couldnt get it back on, a couple of the bolts started, but a few wouldnt. After lots of fighting and cussing, I got them in and tightened. I had to remove the intake a couple years ago (forgot why) and it was another fight to get it back on.
Now I am getting ready to swap on my MPFI intake, and I dont want to have this problem again. I want to be able to just set it on and bolt it down. So, when I take it to a machine shop, how much should I have them take off the intake? .010? .020? .005?
I have no clue, anyone been through this before? As far as I know, the block has not been decked.
