By headwork I ment valves, port polish . But that's good to know that stock cams can make decent power

theyre ported and polished aswell, stock hardware in it though as far as valves and springs and such

YOu need to be looking at the overlap

can you give us more details

you dont want the intake and exhaust valves open very much or at all with a boosted application. so you have to check the overlap to see how long they are both open

^exactly - high exhaust backpressure because of the turbine in the exhaust path actually makes milder cams with less overlap sometimes more desirable than "hot" cams designed to extract every ounce of VE at high rpms in a NA engine. tubular vs log manifold in your kit may have an impace in your cam choice. str8dum1 I think would have many more options than those of us with a log manifold.

Yeah our stock heads flow pretty damn good even at high HP... but like st8dum1 said, its more about he design of the cam... cam choice will completely change the attitude of your motor, it can go from awesome in the mid range and fun to drive light to light to a biotch in the mid range and a bear to get to idle but will run like a raped ape up top...

HR cams have like 4 more degrees of overlap vs rev up cams, otherwise they have the same duration and lift.

The revup/hr cams are just about halfway between DE cams and 264's, so it makes sense that they can flow a respectable amount of power.

It seems that with a 1/2" spacer and rev-up cams (+hr springs) in a DE you can make power all the way to 7500, which is pretty impressive.
