Running in an emod class for next year. Thinking of trying the vortec bowtie heads but unsure of runner size to choose.
355 w/ small dome
15 in. vacuum rule
4412 willy's
edelbrock 2814
2500 lbs
would like to turn 7000-7300 rpm
So which heads should I be looking at? The 185cc or 225cc head? My gut is telling me to go with the 185cc for the throttle response, but will they give up higher rpm?
