An update to this thread i start. I changed the gear and bushing, i changed to Hughes "melonized" gear and i have drive it for about 800 miles more now and checked it, it has no visible wear at all now on both intermediate shaft gear or the gear on the cam and i drive this engine with a Milodon high volume/high pressure pump, external oiling and Valvoline vr1 20w-50. Hot engine just over 20 psi idle, 2000 rpm just over 40 psi, 3000 rpm 60 psi and so on. Main clearance 0.0033" rods 0.0028" and pushrod oiling aswell as oiling from number 4 cambearing through the rocker shaft. Its running great.
