I have doubts about the volume of the intake ports, the exhaust ports have 80cm3. Any advice??

Thanks.

the inlets are quite big already, just clean the surfaces and remove any casting lines

I'm thinking to weld up and modify the combustion chambers to increase the C.R. without ¿skim? the head. And because the stock design don't burn very well all the fuel.

vocky

will the valves still open ok dunno..

Also won't u lose some flow of the gasses around the back of the valves where it opens if u weld that area up?

There would be no problem with that, in theory, better fuel burn.
