Hemi rebuild questions

Just checking with you guys before I order my parts

ROD - Im using the stock piston, what size rod should I get
VALVES - will the NR stainless 27mm/25mm valves fit in the stock head seats
PUSH RODS - is 5.440 the correct length for use with stock rockers

Any help will be appreciated
you need to check the in the hole measurement before getting a non standard length rod as a lot of the hemi predators and not in the hole that much. You want a minimum of.025 (.030 to be safe) between piston top and head. (include head gasket thickness in this measurement). The 3.303 is the std length the 3.323 rod is used on a lot of the predators that are .030 to .045 in the hole.
