[QUOTE="Mhatlen, post: 1520841, member: 14173"] How did you come out on this ? My thoughts are all you need for the heads is surfaced o-ringed with 425 ARP fasteners. The pushrods by all means get updated. Lifters if high mileage or engines been pushed hard at upper rpm’s from a heavy foot. Then of coarse ALL updated HPO parts. That’s the bare minimum ^^^^ Rebuilding both heads with bronze guides new valves & springs if the trucks loved and long term. Resealing the injectors and HPO system along with turbo rebuild is very wise. I paid the obscene price for the 625’s when I went through mine but I wouldn’t do it again or suggest it to anyone that’s under 500 HP because the 425’s w/ o-rings is all you will ever need. I still haven’t seen any failures on the forums with those properly done. Know several people running 425’s with 600+ HP and hammering trucks without a issue. Post up your outcome if possible. Inquiring minds want a conclusion. :) [/QUOTE]
