Ok, I've got a TD shortblock on the way to me...so here is my question.
I believe the only difference betwene the NA and TD head is the valves are made of different material to handle the additional heat from the boost.
Is there any other difference, or when I rebuild my NA head, can I just have the TD valves installed?
Also, I want to make my own manifolds, is there anyone making the flanges to fit the intake and exhaust so I dont have to make those too?
