PRC 247cc heads. Who's actually used them? Wanting to stick A set on my 416 but haven't actually seen any Real world results from them. Flow numbers are good, can get them in any CC I want, etc.. but would like to see some setups with them. Who's got some?

My car made 571/522 on a loaded dynojet with 93. Its a FAST 102, PRC 247, 251/259 cam 408. 11.5 comp. It went 10.55 at 129.x but I'm bumping out of gear and 60s are mid 1.6s. I can't leave hard with it. I was shocked with the numbers. I was skeptical on my numbers but unloaded the car made 535, loaded the dyno power went to 555, then pulled the air box lid (FTP 104 and CHRS1313) and the car made 571. I would say normal dynojet my car would make upper 540s.
