parts needed for 420C engine overhaul

[tx420fan]

We got the engine boiled and bored and crank ground and now have a complete parts list. I need the following parts to return her to her rightful state:
.090 oversize complete engine overhaul kit

Replacement rocker arm assembly

valve springs

Gasket kit

Rod bearings at 50 under

Main bearing at 20 under

Any help with locating these parts at the best price would help me greatly!
Thanks & God Bless from Texas

I either have or can get all of the parts you listed. The one question I have is on the rod bearings, do you actually mean fifty under? If so, there are no .050 rod bearings, you crank is shot and you will need a different crank.
