Re: The last time I ported a set of LS1 heads I got these flow numbers Not bad gains. How much time did you spend on them? I've ported my own heads before on projects, but the bottom line is porting heads is the most boring work you can do. I'd much rather pay someone to do it, and spend my time having fun.. <img src="images/icons/wink.gif" border="0"> <img src="images/icons/wink.gif" border="0">

A lot of time, but it's worth it. <img src="images/icons/smile.gif" border="0">

Those are last time. I'm going to try to squeeze some more out of this next set. <img src="images/icons/smile.gif" border="0">
