I just figured I'd post the final details of this job.

These heads use valves the same length as Indy heads, and I used 2.19/1.81 valves in this set.
After remachining the valve seats the installed height came out right at 1.900 with a .060 spring cup and a Comp Cams 10* steel retainer with std height locks.
Ti retainers could gain you about .030"-.050" depending on what brand and part number you used.

The chamber volume was right at 82cc, again..... This is after cutting the seats.

The decision was made to shoot for 72cc.
I guesstimated about .0055" per CC, so I cut them .055".
As it turned out, that was worth 12cc, so they ended up at 70cc's.
I took .066" off the intake surface to get the manifold to fit correctly.

Mocked up on an uncut 440 block with .040 head gaskets and Superformance .062" thick manifold gaskets, the bolt holes and ports lined up pretty well.
The 6412 std port intake gaskets are a pretty good match for the port sizing and alignment with these heads.

Heads are assembled with Comp 928 springs, 749 retainers, 611 locks, , steel jacketed viton valve seals, and 1.680 OD spring cups(which required no machining to fit).
