Well, that's what this Forum is for. Teamwork in action.

The GT40 heads may add something to a more or less stock 302, but when you start approaching 400 ci, the equation changes. These things need to breathe, and 1.94"/1.54" won't cut it.

TFS, Ede, and AFR with 2.08/1.60 is a good starting point. The 2V Cleveland heads had this configuration.

Take a look at the Blue Thunder 351 Cleveland aluminum heads on a 400+/- CI engine and see if anything "stirs" inside you! Play with some numbers using Dyno 2000, and see if there are any potential ""Chevy" beaters with these compnents.
