3.2 heads on 3.0 block

[2ManySHOs]

Question, if you put 3.2 heads on a 3.0 block, and you use 3.2 head gaskets.... will this work okay or does it create issues. The gaskets overlap into the combustion chamber slightly as the bore of the 3.2 is larger. With this combination, should you use the 3.2 cams or 3.0 cams on the 3.2 heads or? Need to know as much about this combination as I can as if this is not a good combo, we will abort and go another direction. What is different about the 3.2 heads other then the cams compared to the 3.0 heads . I know you have to modify for the alternator and the coil brake but other than that? Thoughts?

We used a 3.0L head gasket on a 3.0L block with 3.2L heads. The gasket matched the bores perfectly, but there is a ledge above the gasket. My position is that there isn't significant combustion ocurring up there anyway, so having the ledge should be no big deal.

3.0 heads and 3.2 heads are virtually identical. You can use either head on either block. That is not the issue here. The question posted was can a 3.2 gasket be used on a 3.0 block? You match the gasket to the block, not the heads.

There is a ledge above the gasket on both 3.0 and 3.2 heads, because the combustion chamber is exactly the same.

Well that makes more sense then.
