don't laugh big cube guys. i gotta work with i got. i don;t have the meens to swap out the engine, besides this little thing goes pretty good. however, i would like some advice on head choice. i've herd and see build ups the use vortec heads, but i;m not to keen on replacing my new intake. the guy at the parts store of course wants me to buy some aluminum performer heads. there like three times the cost of the vortec heads. are performer heads that much better or should i just bite bullet and buy a vortec kit. swaping really isn't a practicle option for me. please limit making fun of the 305 to one or two per response (hehehe) thanks.
