Yer the te37 idea is out the window for now, cant afford/rare to get gravels in that size.
Anyway some good news for the day, picked the motor back up from the machinist. Everything looks awesome, here's what i got done:
-All parts acid cleaned
-New stainless welch plugs
-New rod bolts & Rods re sized
-Rod small ends honed to make small port pins fit (full floating)
-Block bored & honed 0.5mm oversize, to suit new hi-comp small port pistons.
really happy with how things are going
