What heads are you running now? On a 402 I would do TFS 235s.

MAST LS3 but you will need a new intake and rockers. Very high flows on 4 inch bore.

AFR 230 V2 heads. I made over 500rwhp through an automatic with a 6.0L block and a mild 231/231 114LSA cam. Great heads and it will fit your rockers and intake choices.

Patrick,
Sounds very impressive. Any videos of your new combination? 102 TB too I take it? What do you have for exhaust?

Lots of videos. I used a 90mm TB to make 506rwhp. With the 102mm TB, it made 511rwhp. It's all outlined here: L92 heads off, AFR 230 V2 heads on, 504rwhp 6.0L automatic! (now with track results).

I second that. I am running some AFR 230's on my 421, no numbers yet but I will have some soon. If you are running 4.005" bore you might run into some valve shrouding issues with the big 2.16 intake valves.

TFS or AFR, or even the PRC 237's, all good. If you are wanting some good nitrous runs, make sure it has a really good exhaust port.
