modding 23* intake to -18* head?

I was wondering if anyone over here knows anything about, or knows someone who has modded a 23* intake to fit on a -18* head?

I am wondering what is involved and what exactly had to be done to do so.

do you need adapter plates or weld more material on then cut it back out?

would a stock 23* intake seat firmly between -18* heads?
Would the bolt holes line up?
would the ports only need adjusting?
what about cooling ports?

I saw an old add for a LPE car that had a super ram on a -18* head. I called and they didnt have any info for me on what is involved.

Lots of welding, expoxy and major modding. The heads are completely different. Don't even try, you will kill yourself. It will also cost more for machine work than it would be to just buy the right damn intake in the first place.
