What heads do I have?
I bought a 1976 chevy K10 picckup for the 350 engine and have the engine completly tore down for a rebuild. i'm going to order the rebuild kit as soon as i figure out how much compression I will have with flat top piston the ones that i took out were slightly dished. i found a bunch of numbers on the heads, witch ones tell the combustion chamber size.
thanks Ben ------------------ 70 chevy lwb 350 3on the tree

What is the casting # on the heads? Should be either a 6, 7 or 8 digit number. Something like these:
376445 3932454 14014415 ------------------ 67 SWB 4x4 - 396 BB / SM420 4 spd 8" lift / 15x14 Welds & 35X14.5 SSR's Grants Pass, OR

Chevy70, those heads will work just fine on a mildly built 350. They are 1.94 heads. There are better heads out there and definitely worse heads out there but from what you described of your 350, you should have no problems running those. If you were running a cam larger than 280, I would say time to do some work on the heads.
