Cylinder Head cracking and Intake Manifold!?

What cylinders are cracking? All of them, randomly? Or is the ones closer to the firewall? Just wondering because of difference in flow in the intake. if so a ported intake should help?

Also, can you get the no limits intake elbow that would work with a regular cold side pipe(so I wouldn't need the whole setup)?

I would assume any kind of heat reduction will help in preventing cylinder heads from cracking. I don't know for sure though. I do know that it is presumed that the intake manifold will help in preventing cracked/melted pistons because of the 20% increase in flow to those cylinders.

Not sure on the intake elbow. You would need to call Elite or Rudy's about that.

When I spoke to JD at Elite, he said their ported intakes reduce the air flow difference to the back cylinders to only 1% (a 19% improvement)

Well i want to appologize on my elbow comment. I was thinking that Mike had sent me some pics of one that would mount to a different CAC Pipe, but it was a pick of the mild steel setup where the boot mounts in the same place as stock, but i am not sure if it will actually mound up to different CAC as it is sold as a kit not just an elbow. Maybe PM him, he stays in the army most of the time though

Cool, thx guys.

To avoid any confusion, I was referring to the difference the back cylinders get in terms of air flow versus the front cylinders. I have never heard a number in terms of overall flow for Elite's ported rails vs. stock. Has anyone?
