Can anyone give me the pros and cons with using stock ported heads against using the champion ported heads???(iron)what differences are there if any?I am building a new motor and would like to know if it is worth spending the money for new heads if the stockers(ported and polished)are done professonally by my machine shop???
I have had the block bored .035 over and billet caps installed,line bored,new cam bearings,rod bearings,arp rod bolts,the entire assembly was blueprinted and balanced.....and such
