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

we are probably the largest sanction sealed circle track engine provider in the country....and not a single engine we offer is over 12:1. what random, no rules class is going to let a Chrysler 318..or 360...with a completely random parts list to run in competition?

I'll be glad to help...and we sell comp cams. I just need a budget, and a rules list. And the realization that some guidance is in order :)
