AFR 205 Heads with a G5X3, looking for MAX power w/o flycutting my pistons as that will involved another teardown.
the G5X3 specs were "secret" and its well known its 234/242, hopefully somone can get an X4 measured soon...

The Best V8 Stories One Small Block at Time
X3>>> 234/242 112/114 LSA
MS3 >>> 237/242 choice of LSA (111/112/113)
X4 >>> 240/244 111LSA (Like a MS4 on XE-R or should I say MS4 is like a G5X4 but with LSK lobe on intake)
