HI and thanks for the input! I keep flip floppin' on what to do! 331?? 347?? 331?? 347?? Since it's really just a toy, I keep leanin' for the 347.
I have made up my mind to not go with the gt heads or even gt40 heads. To take advantage of the cam I'll need the 303x heads or maybe trick flow Twisted Wedge or some similar.

Thanks Again for your opinion!
