2.7 cam choices

How much cam can you put in a stock 2.7 CIS piston? Suppose I need options for a regular and S piston with CIS dome shape.

Lets assume induction is not a limiting factor and it will have an early exhaust or headers.

Basically I am looking to wake up a CIS 2.7 by swapping cams for something more fun. Plan is to run on Webers for now.

I have built other engines with bigger cams but they always have replaced stock pistons with JE or equivalent such that there is valve clearance. I have never measured or experimented with valve clearance on a stock piston.
