Same as the auto HT-T 186 cam i think.
the valves are the same size as all red 6 cyl.

I'll check my books, but I'm pretty sure the X2/S camshaft had the same cam timing as the stocker, but more lift.

AFAIK the valve sizes were the same size as the stockers also.

If at first you don't succeed, just call it Version 1.0

Talk to a pro engine builder. It will depend very much on what induction & exhaust you are using, it all has to work in unison as a complete package.

The cost of an Aluminium Head is about $2500 complete with claims of 33% less wait and 50HP compared to stock red 6 head. What HP improvements would a stage 3 yella terra iron head give compared to stock 6 head?
