The pic below is a flow sheet of my TFS TW heads after porting. Do these numbers look good?

The heads were ported for a blown application (Vortech T-Trim).

Other things considered:
I'm using a Comp Cams 284HR camshaft, TFS-R intake, and 1 3/4" longtube headers. Oh, and it's a 306 motor.

Thanks in advance.

IMO, those look like pretty good numbers. However, your cam has .533/.544 lift, and you will never see that .600 flow with that cam.

What cam would you recommend?

A 1.7 rocker would give you .566/.578 lift. As an alternative, the CompCams 276HR with a 1.7 rocker would give you .566/595 lift. It would also shorten the duration, giving more low end torque(over the 284HR) on a 306. Be sure and check the piston/valve clearance using 1.7 rockers. I'm building a B50 331, using the CompCams 284HR, 1.6 rockers, 2.02 valve ported Edel heads, and a S trim.
