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

Valve Shrouding is a very, very real thing. How detrimental will it be on a 360 intended head, with 2.02 valves, on a 3.94 bore. Is yet to be seen.
The only real way is to have them bench flowed on a 3.91+.030 or .040 (whichever you do) pipe. I have seen heads with oversized valves that were supposed to flow 300 cfm, be choked down to 230 cfm on a stock bore block.

you don't necessarily need to bore notch the cylinder, but it may be worth your time now to have them flowed NOW, and to then have the valve un-shrouded on the cylinder head side if needed. (have done this several times)

I don't want to insult anyone that has never heard of this, or assumes it will be fine, but this is exactly how engines that make *** hp on paper, go together, and somehow only make 2XX HP, and can't get out of their own way. Then we all stand around and wonder what went wrong.

I'm also hoping the CR swing of "anywhere from 10.5:1 to 15:1" is a misprint...or we have much greater concerns to walk through than valve shrouding....
