Asking About: Mustang Trick Flow Twisted Wedge 11R 190 Cylinder Heads - 56cc Chamber (79-95) 5.0/5.8


91 GT

I have a stock bottom end 91 Gt. I have an x 303 cam gt 40 intake BBK equal length headers 65mm throttle body 70mm mass air. 373 gears wondering if I should get these heads or the 66cc. Also should I use 1.6 or 1.7 rockers. Thanks for your time

Accepted Answer
The 56cc will give you a higher compression ratio over the 66cc, other than that the heads are virtually identical. The x303 cam is a fairly aggressive cam profile and its valve lift numbers are based on a 1.6 ratio rocker arm. I would recommend sticking with the 1.6
