Pistons for my BBC 402

I'm in the process of building a BBC 402 for my street driven '79 Corvette. I do also play on a few local 1/4 mile tracks so I've sorta grown out of the stock L-48.

I have a 1972 standard bore 402 just about ready for assembly. I'm collected most of my required parts and soon it will be coming to life.

I'll be using a 427 Froged crank and rods, Edelbrock Performer RPM Heads (new) ovalports, Edelbrock RPM Air Gap Intake to match, and I have my Comp Cams Extreme Energy 552/555 lift with 230/236 duration. I plan on running with my current MSD-6AL ignition system and also I'll be using my great working Quadrajet. I have all my other little pieces like push-rods and lifters but I'm just waiting now on my pistons.

I have a set of new cast (stock) which have a rather small dome (.115)and 1 valve relief. I could use these but I'm thinking I'd have a chance of reaching my goal of about 450 horse with a bit more compression. By what I'm calculating here a forged TRW piston, part # L2328F would have a .319 dome and then I'd end up about 9.8:1 compression.

I guess what I'd like to know is if I'm on the right track here and should I just call Jegs or Summit and get these pistons ordered. Can't wait to get this BBC into my car. Thanks for any advice you can give me.
