Cylinder Head Poll

I think the TFS, or AFR's are the way to go, the intake 1ports on the canfields are pretty big, (19* cc if I remeber right), WADS56 seems to be doing good with them, but they're on a blown 347, so.... I'll probably get TFS Track Heats, juts 'cause they're cheap and I'm in High School....

Canfields 192 cc (intake)/60 cc (exhaust)
AFR 165 or 185 cc (intake)/70 cc (exhaust)
TFS 170 cc (intake)/66 cc (exhaust)

Flow ratings @ 28 inches of water:
Canfield 258 cfm (intake)/195 cfm (exhaust) @.500 lift
AFR 165 250 cfm (intake)/191 cfm (exhaust) @.600 lift
AFR 185 282 cfm (intake)/191 cfm (exhaust) @.600 lift
TFS 251 cfm (intake)/193 cfm (exhaust) @.600 lift

I do not know why the canfields are rated at .500 lift but I talked to Bennett Racing and they told me that the stage 1 canfield heads flow 278 cfm (intake)/208 cfm (exhaust) @.600 lift.

The canfield heads are probably a little too large for a natural aspirated 302 unless you are going to turn 7500 to 8000 rpm's.

WADS56 Stage III Canfields 310cfm/230cfm; Sound familiar.
