do it and let us know how it turns out. I have run a setup this way with no known issues.

I run a Jetworks ported 61x cylinder on an unported 61x bottom. No issues to date. I was told by many I'd be better off to port the cases but the engine builder said otherwise on that particular setup.

It will run just fine.Its not going to go as well as if it was on correctly ported cases.
