vortec 305 heads on tpi?

Would the vortec L30 305 heads fit on a 305 tpi intake without any work done? and would it increase power cause they flow better? and if it needs a special adapter plate which one, how much, and if you could give me a link that would be great! or is there a way to have a machine shop make the stock tpi work? Thank you in advance!

IIRC, Scoggins Dickey sells a Vortec TPI intake. They are not cheap- $400. Edelbrock has one also, but it is even more money. No realistic way to modify your current intake. If I was going that direction, I think I would do the 350 Vortec heads instead.

TPI intake ports don't match Vortec head ports as well as bolt pattern ( 4 instead of 6 )needs changing
