Is valve shrouding a concern in a 318 w/ 2.02 & 1.6 valves

I already have a 318 block and crank. I need 15:1 compression, but I don't know if I can afford the custom pistons though... :/ So you can reduce valve shrouding by running smaller valves or by reworking the combustion chamber and notching the cylinder walls? How much space do you need between the cylinder wall and the valve to avoid shrouding?


How do you figure you NEED 15:1? I can tell you as the compression ratio goes up, the tuning window gets smaller. I will not go over 13:1 for anyone unless you have a track record with me of being able to tune compression that high.

And then, you posted a comp cam. How did you get that cam? You don't want that find and 15:1.
