If your heads are set up with 1.850 spring height. I am going to assume you are running at least .100 long valves. That will require different pushrods.

Bobs right....
You change valve height according to valve lift and also requires a pushrod change....You DO NOT want to change valve height till you change cams messing with one or the other will throw off your valve train geometry.... these all need to be done at the same time.... read this here....http://krpracing.com/technotes/ click on valve lash...TN5

on small cars yes. but fat fender cars are pretty much the same in size and weight as the donor car. i found s10 brakes work great on fat fender and pickups. a deuce will just need manual brakes...
Time for brakes
