Difference in Cylinder heads?
I've got a quick question. I was wondering what the difference in air in head and Air in Manifold? I've did some searching on here but couldn't find anything? I was wanting to get another head and port and polish it and get it all ready and swap it onto my truck. Any help appreciated. Thanks

You might want to put on a head for a 240. That will boost your compression half a point. Of course if you port it, and you absolutely should if you want more performance, then you will need to dial in that carb again.

air in the head has the air injection cast into the head. in manifold has fittings, and tubes in the exhaust manifold,the 240 head is a great option, but the efi heads are fast burn. kinda evens out on the compression
