i'm building an ITR motor dart sleeves cp pistons eagle rods looking for 450+ ETC... now i'm debating on leaving the head stock just refreshing it new seals, guides ETC. but i was'nt sure about cams should i leave the stock Type R cams or go with something aftermarket if any 1 has done a build with a type r head let me know ur results

 

Ambitous project... I have heard mixed opinions on this, from GSR cams to R to Aftermarket...

I'm not too sure, but GL on your project.
