He has tons of time in porting/polishing/blending in those heads with a shaft mounted rockers,solid roller cam,etc. it's not an amateur build for the avg person. Also not cheap. Very cool buildSo what's the true secret to achieving the 333 rwhp w/ e7's? If i was to buy a TFS top end kit for nearly $3k i'd only maybe net 300 rwhp. Where are you getting ahead on a less expensive setup (I say less expensive because you don't have $1500+ in alum heads)? Are the heads reliable after all the porting?
