the first thing you should do to this engine when you have the pan off is change the oil pump to an m-72.-melling oil pump.
The factory oil pump pressure cutoff/bypass is too low in my
[email protected] want 60-70psi
Second thing you want to do is change all the freeze plugs, brass is good.
Timing chain and decent 260 degree cam would be a great idea.
Get a good set of plug wires, like Taylor spiro pro- 500 ohm resistance or msd-50 ohms resistance. Stock style -1400+ resistance...
