Is the 1.6 exhaust valve too big for LB9?
I will be cleaning up my stock heads and will be installing larger valves.
1. Will I be able to fit 1.6 valve in the 305 head?
2. What areas of the heads I have to mainly concentrate on?
3. I have a swirl type head. What would happen if I would move the swrirl ridge over a bit or even get rid of it?
Any other tricks to improve flow?
Thanks.
PS. I have decided to stick with my old heads.
