 FS: 706 Casting 5.3L heads
Hey Everyone.
Ive got a set of 5.3L 706 casting heads off my 2003 LM7.
They have had a minor bowl blend on them, smoothing the transition to the valve seat and smoothing the ports. Swirl ramps not removed etc.
They have less then 5k on them, in mint shape. Ill trade for 241 or 243 casting heads.
Great for a further porting project if you want to upgrade the valve size etc. Smaller chambers = higher compression.
Asking $150
