My point is you didn't buy them until 2002....but they were released in 1995. So, theoretically...the heads were out for 7 years before YOU got them to perform at that level....correct?
Conversely....it took you a very short time to make your mark w/ the pro ports. A great head shows results...and "fast" you say. Look at the time span between when the RPM's were 1st released and the time it took to put a N/A street car into the 7's.
You should have the Pro ports in the 7's this year...assumably. That makes the pro ports WAYYYY better than the RPM's..right? Just tryin' to get a handle on the logic that is being used.
They (RPM's) were out for 17 years before Jack got them to perform at the level that HE is at. I haven't followed the dates on Jeff's milestones....but it hasn't happened overnight....more like YEARS. Many years since the RPM's were released. Just tired of hearin' how the CV-1 have been out for SOOO long. Not really that long in the grand scheme of things. A few have hyped the cv-1's up and regretably...too soon. My CV-1 engine made 705 hp and I spec'd everything but the cam. I'm a truck mechanic by trade. I can weld, paint, wire and just about anything else when I put my mind to it. I'm not an engine building specialist by any means....but 700 hp on pump gas is fine by me...for now.
