GOOD BRAND OF HEADS

[viper0824]

LOOKING TO GET A PAIR OF HEADS FOR MY 97 COBRA I looked
at patriot heads but diddnt see any for the 4 valve. how much hp increase should I expect?

on the 4v's i think all you are gonna find is ported stock heads, especially on the "b" heads like you have. i would expect pretty decent gains, but nothing worth taking the motor apart just to port the heads.

CNC ported FRPP 4V Heads

FORD RACING HIGH-FLOW 4.6L DOHC 4V MUSTANG COBRA CYLINDER HEADS 03-04 Mach 1 Ford Mustang

Intake and exhaust flow 15%/29% more respectively

Only drawback is that the 96-98 Cobra's need the 99/01 Cobra intake for them to work
