I'm installing a Thunder Racing 220/220 .561 lift 114 duration cam this week.Other mods are FLP's,Corsa,Lid,MAFT.Without Cam I'm pushing 340hp/350tq.
I got this cam for emmisions.
What kind of gains should I expect with ported heads?
What stage should I look at?

Slowhawk i think stage one(typical) heads and cam should be worth 70 hp at rear wheels. I will let you know what similar cam and stage2 heads are worth in about 3 weeks.
