906 head porting

Stealths are $1100, plus the valve job, plus the springs, retainers, and locks. Plus the bolts. Plus the right head gaskets. Works out to $2100 or so for me ready to install them.

But- walking in with a set of iron core heads will cost $1300-1400 just for the heads refurbishment and new valves, seats, etc. Then the porting which if it had to be paid for I'd say another $250-300 for something up to a stage II level. Asuming reusing bolts and the head hasgets in the gasket set.
