Mark,
In rough numbers every .001" of head gasket equals 0.22 cc's

Is it possible to do a combination of things ?

David Vizard talks about putting a radius on the valve relieves which he says helps improve flow.

Opening up / soften the combustion chamber

Finally increasing head gasket thickness.

Opening up / soften the combustion chamber: DONE. Chambers are at 78 cc

Finally increasing head gasket thickness. Yea, is where i'm at. Thanks

Tally done. The CYLs lack the factory chamfer. Wonder if i go long on unshrouding CYL chamfers.

Dang Slugs are at zero deck.

Working with some serious looking internals for the project. Aluminum rods, look like maybe GRP’s? Be a shame to drop the compression with guts like that. Its saying let’s ROCK…

Forged crank, BME Rods (+1 GRP matched replacement). Good block.

Maybe best to trade this Flattop shortblock for a dished 455 shortblock!
