[Fot] TR4 Block work suggestions

[John Styduhar]

I also have the center plug hole on the main oil galley tapped to install
an NPT adapter for the oil line from my accumulator.
Have the shop check the alignment of the mains and line hone if necessary.
Machine the center main cap to install a reinforcing strap.
Bottom tap all head stud holes.
Remove and tap the front and rear main oil galley plugs for flush-fit NPT
fittings. Have this done on the cylinder head cooling plug.
Remove the crank scroll and install a rear main seal conversion. Do not use
Indian Head Shellac on the felt seals.
Grind unnecessary casting material from the inside and outside of the
block, particularly in the cooling areas.
If needed, clean up the mating surfaces for the liner gaskets.
