custom .450 lift cam
flatops
stock crank/rods/stroke
4412 carb
94 octane gas
locked HEI

have two head options: milled 882's or stock 993's(mexico ones) either one with .015 steel shim gasket, stock valvetrain. I know both are NOT prefered heads but they are what i have!

Secondly the 993's have "flat" bottom exhaust valves, 882 are dished. whats the diff?

opinions? TIA

If it helps I asked a similar question about a month ago roll down the engine tech forum and find 441/487/993 vs EQ heads and you will get all your questions answered I think 993 all the way even if you have to have them cut.

882's are prone to cracking....I'm guessing the iron in the mexican 993's isn't the best...and I think they are a later production head....might have to come down to a coin toss...lol
