bowl blend eh? id try to do it myself but i dont want to mess up my heads. more then they can use? how much hp do u think these will get me over stock 318 heads? i guess when i get them port polished i could get the bowl blend done. i just searched it. sounds complicated. but worth it. alott more air flow. hopefully i can start rebuilding my 318 soon. im goin for balls out hp. cheap tricks. anyway i can get the power.
