AT LAST someone else came in with the true costs of milling heads. Years ago I was quoted $180 to do a skim cut on a pair, but that did not include the intake faces. Now add the extra charges for the time to go 0.060, which is really a lot of passes at least on machines I know, and you may well be looking at $500 for the complete job.

BUT didn't the OP say way back in the thread that the heads have been milled a bunch? So isn't the whole "mill the heads" comment worthless?

The real way to increase power is to increase flow and the head swap is the best way to do that. We now have a sort of stairstep of heads, each with increasing cost and airflow. But as the Stealth heads are least or close to least cost and offer flows way above stock or pocket ported 906s or 452s or whatever, that's where I would start looking.
