I am currently running stock LT1 heads with GM LT4 hotcam spings, retainers, 1.6 roller rockers and and a heavy duty roller timing chain set. I have the hotcam also installed 525 lift 218 duration and i am wanting to bring out the most in my cam and upgrades by installing heads. If anyone has any head suggestions ie. brand or port work please let me know. I have had the car on a chasis dyno numerous times for programing etc. So far i have managed to get 297 RWHP which i figure is between 365-375 hp off the flywheel. The altitude here in Edmonton is 2240ft. I want to reach approx 425hp at the flywheel and im hoping upgrading my heads will do the trick. If anyone has any suggestions for cylinder heads please respond. thankyou

As well as the cam and rockers, i have upgraded the exhaust added SLP headers, Flowmaster 3" catback exhaust, removed my catalytic converters, moroso custom c/a intake, TBI foil and added every other bolt on imaginable.
