2 sets W2 heads, strip dominator intake

I have 2 sets of "810" race series w2 heads for sale. I also have a matching holley strip dominator intake that fits both sets.
Set A has used 2.02 intakes, 1.60 exhaust valves with 3/8 stems. Has been heavily ported, purportedly by diamond/Elkins for petty. No proof, just what was told.
Set B has new 2.08 intakes, 1.60 exhaust with 11/32 stems. Has been heavily ported by Diamond/Elkins and is marked as such.
Both will need some epoxy from the extensive porting. Set B will need seats.
The intake was an oval port w2 manifold converted to rectangle port.
I'd like 600 per set obo for the heads and 350 for the intake.
I would take 1350 for everything.
