HELP!! need experts advice on 440 trouble.

The header leak theory has been ruled out so it leaves the head and the intake, I sprayed carb cleaner all around the intake and its good, too bad I have to screw with that now. I have decided to pull the heads tonight and have them gone through. When reassembly time comes, I will check back with you guys because I thought I did it right but I think not checking all of the head bolts after break-in was a mistake. I think I will get some new ARP head bolts also.

Are their any suggestions out there for going through the heads? I have a Lunati cam kit with the springs, retainers etc... but what of the valves and the seats and guides? If you all were building an engine that was going to be 10% strip and 90% street (mustang killer) what would you have done to the heads?

One FABO member said if the heads are decked on the block side then they have to be cut on the intake side too, can you confirm that and how much of each would need to come off each side. These are RPM heads, maybe milling them isn't even necessary.
