head specs, please? - Third Generation F-Body Message Boards

hi guys.
i have a camaro with a 350 (5.7) engine on, (just bought) and the casting numbers on my heads are 14102193, on the car said, cross fire inyection. that's ruined so i'm going good old carb, but i believe those heads require a special manifols 'cause of the center bolts positioning, is that true? anyway it will be nice to me to know about the specs on the heads, things as...how many cc's on the combustion chambers and valve sizes?
the block is 100054727, and as per mortec is a 86 and up 350, so i believe it is the 1pc main seal?
thanks to all.
Fernando.

All cross fires were the old pattern.

If they are 350 heads, they're 64cc and probably 165cc runners or so. Valves will be 1.94/1.5

Somebody's done some mixing there. The heads are '87-up 350, so, the cross-fire had to be modified in order to make it fit.

The block is '86-up 350 (I think you have one too many zeros in that casting number), therefore, as it says, one-piece rear main seal.

You need an '87-up intake to use those heads, or modify the center-two bolt holes on each side of an '86-earlier intake manifold.
