If you think you have a cylinder head issue, try running a leak down and/or bore scoping the suspect.

You can interchange 3.2 and 3.4 cylinder heads within certain bounds and caveats: Both engines need to be 5 chain designs to allow this to happen as there were no 3 chain 3.4 engines. The 3.2 heads will increase the compression ratio a small amount due to their very slightly smaller chambers, and both use same camshafts. There is also some difference in the intake arrangement.

3.6 heads are not usable because of the VarioCam+ .
