I've asked a few well known engine builders and also said the same thing, "its been done before".

Plus, at the time I swapped out heads, I wanna to tried it to believe it. It wasn't stipudity but curiousity. Same goes with re-using OEM headbolts.

There's alot of stuff I've done on my engine to proved if it works. Plus, I don't care. If the shit breaks, I know personally its my fault and fix it right frist time.

There's alot of stuff out there that I don't ever see people post about it either.
