The 240cc 4.125" bore head has been on and off the flowbench several times over the last two days, we are going to digitize it as soon as the .400" number hits 290 cfm, right now it is at 286 cfm, it is 236 cfm at .300" and around 330 cfm @ .500", which is good, all with a mear 2.08" valve, as opposed to a 2.16"-2.20" like the LS7/L92 stuff. That much flow with that small of a valve will translate into a head that is easier to cam and to make power with than what the LS7/L92 stuff has been.

Its a pretty recent thign within the last couple weeks. I talked to Arty about the sprigns and the stuff we run and what weve test with and he said they have a meeting about it a few days later, guess they decided it would be a good idea to put a better spring on them all, good call, less hassletation!
