Since I'm going to be pulling my heads for new gaskets and studs soon, I started looking into replacing the pushrods while I'm at it. I'm a little confused about the shorter (.047" shorter) 6.4 pushrods. I've seen posts where some people say that Ford made the 6.0 pushrods too long from the beginning and the 6.4 pushrods are the fix. And I've seen other posts where guys are saying that going with the shorter 6.4 pushrods will make your hydraulic rollers pump up more in order to take up the slack and could cause some other issues.
On a motor with around 200K miles on it......what's the real story on the 6.4 pushrods? Should I go heads and install them, or just leave the stock 6.0 pushrods in there? If I do need to install the 6.4 pushrods...are there any types of adjustment that needs to be done (like adjusting preload on gas motor lifters)....or just drop them in and go?
Thanks!
