That’s not likely.
By the time the heads have been disassembled, cleaned, seats touched up, valves refaced, parts cleaned, reassembled....... plus shipping both ways....... you’ve got a few hundred $$$ before any porting has even been done.

I tell people all the time....... if you’re not doing something where there are rules dictating that stock heads need to be used....... you’re isually ahead using aftermarket heads.

I’m happy to work on the stock heads for those customers who have to use them...... but they really shouldn’t be someone’s first choice...... if “bang for the buck” is part of the selection criteria...... and you’re not going to do the porting yourself.

Speaking of which...... that’s the best bang for the buck........ bowl blend your own heads.
