Ported and decked heads for the Vette:







CR increased to 11.8:1, exhaust flow increased by 18%, intake by 14%. Should be a nice increase in power.

Notice how the stock heads have round chambers, the decking took them down to heart shaped smaller chambers.

Nice work on those heads. Any other changes or just the heads?
No other changes, I'm keeping it stock cubes (big already) and no power adders. Well, hardened pushrods (had to be a little shorter due to the decking) and ARP head studs. I could have kicked the CR up another three tenths or so with different head gaskets, but I'm skeered of piston to valve clearance.

Prices are on the Texas Speed website, lot's of different options. I went with stock (expensive) titanium intake valves and stock sodium filled stainless exhaust valves. Cha-ching.

Well the cam is big, and really needs good flowing heads to show it's stuff:

242/254 @.050", .657/.648", on a 113 +4

Valves are as big as will fit in a 12 degree head, 2.20" intake, 1.60" exhaust.
