Agree with compression and leakdown. besides fixing PCV, and maybe doing valve seals. Nothing else on engine should be done without both tests above.

I also agree on keeping 430. maybe it's not the easiest or cheapest, but if we all really wanted that, we could drop in 400 HP EFI LS motors for way cheaper than you can build a 390 (or even an injected smallblock ford).

Not sure if they are done yet, but this guy claims they have wedge pistons in the works.
