The market for the basic factory BBM iron heads is shrinking.
In my shop, if you brought a set of used factory iron heads in, that basically needed nothing, but wanted them fresh before you bolted them on your engine...... you’d have pretty close to $400 in them.
I can’t remember the last time I had a set come through the door that were in good enough shape to only need that much work.
I have a set here now....... came off a motor that was done only a few thousand miles ago.
They didn’t get hardened seats(and some are starting to recede), original guides which are kinda loose, and I can’t quite make out what’s going on with the valve job(the seating surface appears to be very narrow and not well defined), and they’ve never been milled.
But the bowls are blended.
They will be getting ex seats, all new guides, valve job redone, updated for Viton seals, and milled.
Yeh...... they’re gonna shoot right past that $400 mark.
Edit- I cross buffed a couple of seats to get a better look at what was going on with the valve job.
The seats are actually a normal width.
I flowed one to check the bowl work.
The intake valves are back cut...... and the flow is 240/

These have more bowl work done to them than what I do for the basic job on a Stealth head......and the last set of those I did went 277/
