Hi i just need some info on valves before I place an order tommorow.

i will be porting the head and getting the cam reground so whilst getting new valves i was thinking to get A14 valves which are 2mm bigger in the inlet and 1mm on the exhaust

so my question is can i just use the same A12 valve seats with the bigger valves with no sealing issue?

the inside of the valve seat will be opened up abit so it can flow more with the bigger valves.

Thanks!

why don't you just put a oval port head on it, which will have the bigger valves /ports already,(you will need to change inlet manifold as well for oval port head).cheers

Yer it makes alot more sense to do that but have to get a manifold and heads arnt cheap either

Most of the cash goes towards university fees so just trying to work with what i have haha

Thanks

The exhaust seat can be opened up BUT the intakes will need to have the seats replaced if you wish to install the 37mm intakes.
