Upgrades I did include ARP head studs, and 20 thou milled off the pistons. Like Dave mentioned, you can get newer valves and rockers, but it really depends on how much you want to spend on this build, and what your expectations are.
with all the goodies, what does this add up to $, ARP's, 7.3 valves & rocker arms, valve job, gaskets, misc. parts disassembly, labor complete?
NO lower end, strait valve job upgrade...Thanks
