I'm thinking of trimming up my vavle openings and dropping larger valves in my head, I just want to see if its actualy worth doing. and get some feed back from other people who have done it. I am going to turbo charge it so it would make since to give it more breathing room with larger valves.

 

bump need some disscusion

 

unless you plan on opening the throat, then it will do no good and you will only block it more.

 

throat meaning intake?

 

Throat meaning the head ports directly before the valve. W/o porting the head or enlarging the seat, it doesn't do much of anything.

 

oh well i have already done port matching on the head from the intake and from the head to the exhaust manifold
