K20a3 Block with k20a2 head, thoughts?

[Jdm.]

Hey guys I was wondering what you guys think of the set up above?
The owner blew the old k20a2 with worked internals, k-pro, toda c spec cams etc..
He now wants to get a k20a3 block and incorporate the internals from the blown a2, and combine it with the previous a2 head.
What are do you guys think about this?

K24a3 block instead

I know, that would be the best way to go, but he already has a a3 block so just wanted to get opinions on that set up?

afaik the main and big difference between K20a3 and a2 is the head. I read this yank port and polished an a3 head and it still didnt flow as good as an a2. the blocks should structurally be the same. never heard of someone put a a2 head on a a3 block before. I think your the first.

Yeah I think I am, I've searched around and haven't found much info on it, maybe it isn't the best way to go, but idk. The a2 head will be going onto the worked a3 block, I'm just not sure if anyone's done it before
