Maximum Performance N/A 383 build. Input wanted from engine gurus.

Trick flow says the 240 heads will not fit on the 383. I wanted to put them on mine but apparently it will not work.
I just cleaned up my 346 heads on my 383, I decided that all the aluminum heads are awesome, but they are engineered for a large bore, which inevitably means the Intake valve is shrouded by the bore, notching isn't a good solution, in my opinion.
