302 heads...were to buy..what works with..?

I have a 318 block with forged 273 crank that im itching to take to the machine shop...

i hear 302 sworl port heads are the way to go...i cant find a set...were can i buy some? and what are the full casting #'s?any online sources??

im going .30 over and want to have the block zero decked..

im thinking getting after market pistons to bump up my compression and use stock heads??any ideas with this and what pistons to buy...??

or find 302 heads and use stock pistons ??because i hear after market pistons with 302 heads wont work on the street due to to much compression...??

i want to build a radical street machine and still use pump gas,,thanks fabo:banghead:
