Hey guys whats up, The kit came with Pro Comps 1.6's, but with my cam I'm going to use Comp 1.5's. As far as the pushrod grinding we havnt got to that stage yet, we are almost certain that there will be some clearancing necessary. but nothing major. I have to say Iv heard alot of mixed emotions with these heads but for the price I'm not concerned with alittle bit of extra work. Im very excited to get this together. As far as that water pump, that is off a 62 413! with electric pump!
