Cylinder head compatibility

[Restless]

Is the 3H5 cylinder head compatible with a 2H7 motor? The cylimder head I ordered comes with cams, valves, and shims already installed.

No, but that's the short answer. Need more info to elaborate.

What info do you need

No, don't do it, the compression will suck unless you change the pistons too, if it was the other way around then yes.

Well here is what I'm dealing with.

1. 3H5 motor with a destroyed piston and rod as well as a useless the cylinder head.

2. A 3H5 cylinder head on the way via ebay with valves intact

3. A 2H7 motor with all good pistons but no cylinder head

So I'm trying to figure the best way to get a complete motor. If the 3H5 motor will not play well with the 2H7 cylinder head then do I have to split the case to replace the rod that holds the piston?

It will be fine. Just not as much compression. I run a 81 head on my 78 runs fine.

No, but that's the short answer. Need more info to elaborate.

I'm curious what the long answer is. If it is just compression loss I am going to go for it. Is there something else i should be aware of?

Thank you e30 gangsta. I was startimg to feel hopeless
