Don't get it right, just get it running. 85 318 roller

Performance wise, no. Even more so with a 2.02 that will need to be ported to allow for the valve to actually be a benefit. The area under the valve has t change much at all and flow is impeded.

The 302 heads can be ported out very well for small displacement engines. With his 308’s ready to rock, that becomes the clear choice.

A 302 head is not the answer to anything unless it’s a stock rebuild or it’s heavily ported and heavy porting is what it will take.
Agree with everything you said for performance build.

I also would run whatever I had ready to go. I must have missed that part in the original post.

For a basic rering though if everything else is equal and you dont have another set of heads ready to run then there isnt any need to spend extra money to upgrade just the heads. Thats all i was getting at.
