sweet, also I've been told that if I'm replacing the pushrods I should also replace the rocker arms too. Should I do this or can I get by with using the old ones

judgement call for sure. the rail on the 4 is tightened down with little to no adjustments, so all pressure is done from the lifters. and usually the lifters will pump up to fill the gaps needed. depends how deep your pockets are to replace all the rockers. on my 4L builds and head work i just leave them. if you notice any problems, they are easy to get at down the road. its not like you need to pull heads off to change them.

hope that helps. sorry i can't give you an answer for that. as said, your call.

Alrighty, also would anyone happen to know the specs for a 4.0 pushrod. Like its length, diameter, and ball size
