I recently traded for a fully built GSR head w/ some custom crower cams, which are ment to go up to just under 10k RPM's- i have no put it in yet.

I have little to no knowledge of what is done to my motor, due to the previous owner was simply in a hurry to sell it to go into the marine corps, so i cannot ask him questions on what is done.

But I do know, he had a chipped/tuned ECU (kept it) with no rev limit, so is there a possibility the head is built with titanium goodies as well? I've also come to wonder if he had ITR/CTR cams installed, as the difference between the cams is only a bit beefier on the crower's.

So any way to tell if I've got built head components? Or also, whether the cams that came in my motor are GSR's or not?

 

get em measured....? maybe crowers have special markings on them?no clue on that one tho
