[QUOTE="4VandHemiKiller, post: 16043672, member: 49914"] Increased head-flow/port volume reduces camshaft duration requirements. So if mild cam timing is a build criteria, ported heads would be ideal. Also while stock GT500 heads with their ~ 310/240 cfm flow numbers (@ 28") flow very well, picking up another 40/60 (I/E) with a Fox Lake port job would free up power, and the chamber softening Fox Lake does will make the chamber slightly less detonation prone. To the OP, just keep in mind the Fox Lake CNC program adds ~4CC to the combustion chamber, consider that when figuring compression. Fox Lake has the best 4V/GT500 programs; IMO, and the most consistent valve train setup (lash adjuster preload). [/QUOTE]
