Thread: L32 heads on L67

OH i was thinking of the na block in the 97-03 my bad

Both use 1.52" exhaust valves and the same head casting #4781. The L67 uses a 1.8" intake valve vs the L32 uses a 1.83" intake valve. L32 bolts onto the L67 block, but not worth it unless you're running serious mods because as copgtp said, the difference is minuscule. If there's nothing wrong with your L67 heads, put your money elsewhere.
