Wax what are the basics you have to do to the cylinder regarding port timing for the 5mm ?

The cylinder is actually quite close to a 5mm porting spec. You need to run the pistons out the top of the deck 2mm and you will end up right on the money.
Im building an engine to rev and will prop down. Im looking at 195 exhaust and 130 degree transfers. The blow down is 32.5 degree which is very close to the money.
Im running a pipe tuned to 7800 with that porting spec I have a small pump and Im going to rev the nuts off it

Hi! I have milled down 2mm from the base of 62t cylinders - what do you think - will it work like that? Or should i do some mods on transfers? Will do the domes too.
