Sergio146 Posted October 28, 2023 Report Share Posted October 28, 2023 Hello, just wanted to know if an l18 block can be used in pair with a u67 head? Just want to know if that is a combinación that I can do or should I look into another head maybe a w58. Quote Link to comment
datzenmike Posted October 28, 2023 Report Share Posted October 28, 2023 Any L4 head will fit any other L4 block, though not necessarily a good idea. The L18 usually uses an open chamber (45.2cc) A87 head. Since the U67 and the W58 are the same size combustion chamber size this won't affect compression. The A87 heads may, but not always, have the same intake valve size as the U67/W58 but the intake ports on the U67/W58 are larger. Can I assume that you have the L18 intake and exhaust manifolds???

Sergio146 Posted October 28, 2023 Author Report Share Posted October 28, 2023 The exhaust manifold is not independent of the intake manifold and they are mated together now that I looked into it. Quote Link to comment
