Have you checked with Patriot Performance? ------->
They have the 243's 100% cnc'd.
What is your ultimate goal for the car?

you are going to like the set up. I am running stock 243 heads with upgraded springs and retainers with a comp XER 228/228, .588/.588, on 112 LSA and dual exhaust. The car is putting down 422 hp and 408 tq at the wheels. Drives mean as ****.

now, I have a question. In my thread, im getting word that with a cam about the size of yours and a set of ported heads, possibly PRC Stage 2 5.3's or maybe a CNC'd LS6 head, that 420 RWHP is unobtainable. Not doubting your numbers at all (congrats by the way), just wondering if the info Im getting is correct.

Well considering I am on dual exhaust and stock 243 heads and have already exceeded that 420 number, they are wrong. Here is my dyno sheet.
