Would I do another set? IF the head is cheap to start with, yes.
IMO, there just not worth what they were new or worth much now since the latesest heads came out.
Flow Sheet - 4.125 bore (Will not be using that bore size)
Flow Sheet, local enghine builder, 4.03 bore
(MAN! I gotta get a better shot of that, sorry guys)
W5 Intake port shot
W5 Exhaust port shot.
On engine

If you look at the pictures Rumble posted you can see how you need to raise the roof. I think it can go up at least .200 or a skosh more, but you can’t, because the SEWER sized valve spring pocket breaks through.

If you raised the roof and floor .200 and used the correct valve job with a 2.125 valve you might tickle 400 CFM. Maybe. It would be close.
