cleaning up the slant six head

I'd love to see some one like Edelbrock develop an aluminum head for the 225 with a modern ~9:1 CR combustion chamber and ports that will support 6500 RPM, even if they have to move the ports & rocker cover gasket rail up to do it. Put enough meat in the head gasket deck to allow cutting it to 11:1 CR and enough meat around the ports so that some guys could get a little crazy. Oh, and an undrilled EFI injector boss on the flat of the head above each intake for pishta. I'd buy one if the economy of scale is remotely close to there, say a bare head for ~$600. Something like that, out of the box, would make my 170 scream!!!
