what kind of heads do you all have? i want to get new heads, but not sure what to get.

 

vortec heads are good

 

i have 305 tpi heads that were ported with ugraded springs and with 1.52 rocker arms. alot depends on if you have emissions or not. vortec heads there no spot for EGR

 

Vortec heads are the best choice; but as stated above, they use the external EGR setup. Vette L98 heads are popular but you will spend a lot to obtain them, and match out of the box flow of aftermarket heads and Vortecs, they dont have EGR and you will have to mill them. World S/R 305 Torquers are a real nice direct bolt on head. They will outflow all the stock SBC heads (except Vortecs) and they are reasonably priced.
