I believe all FT heads have the same cc volume.

The FT did gain thermactor bosses during the emissions era (sometimes machined for thermactor tubes, sometimes not), but the head seems to have remained unchanged other than that.

I believe you'll get about the same compression with any FT head.

Keep in mind the exhaust crossover casting is way different between the FE and the FT, so if you use FT heads you must use FT manifolds, and if you use FE heads you can use FE manifolds or aftermarket goodies. When you speak of 390 heads, I'm not sure whether you are referring to 390FE heads or 391FT heads.

Also, 428CJ rods with the 13/32 bolts are the same as 3/8" bolt 390 rods from mid-63 and later. The only difference is how they get drilled for bolts at the engine plant. At 4000 RPM, there is no need for the larger bolt.
