heads can run anywhere from 600 to 2k just depends on what you want. honestly run by a machine shop and see what they got to offer. i just got a 347 i spent 2500 on short block, im using stock e7 heads i had sitting around, there gonna port and polish job, bigger valves, and the machined for screw in studs, dual plane intake port match, shorty headers, and a x303 cam with 1.6 roller rockers and with that setup the machine shop said i should be around 340 350 range which is decent considering the e7 head will give me 9to1 compression. and all that and im still under 4k
TT 347 stroker
