Which is what it sounds like Jack is going for, considering he wants to put in larger valves in. You can't tell me that Yoshifab's are going to less peaky and have me believe it considering they're mild factory cams, though!
I'm just giving you a hard time. If Jack had reasonably cheap access to Penta cams over the standard B234F cams, I'd run them, too. If I was building an engine for 250hp+ with larger valves, I too would definitely go with something aftermarket if anyone wanted my inexperienced opinion(I have only dealt with a stock B234F and removed balance shafts in the General Leif). Oh, and Harald's gutless at low rpm turbo 16V engine with Yoshifab(?) camshafts.
