SC cams in a 930 - valves><pistons?

There's a zillion threads in here about 930s and SC camshafts (and I've waded through most of them during my lunchbreak), but I can't find a clear answer to the question about valves hitting pistons.
In an otherwise standard 3.3 engine, with SC cams at standard timing, should I expect the valves and pistons to clash?
I am rebuilding my engine for more grunt in bottom half of range and planning to have my turbo cams reground to SC spec. (Also using K27 7200 turbo and some head porting.)
If I am likely to have valve/piston clashing, I'd prefer to know about it now so that I can plan to fly-cut pistons before I assemble the engine.
Naturally, I'll do a clearance check during final assembly, but it would be nice to know beforehand if this is usually a problem.
I noticed on one thread that Rarly runs SC cams but no mention of cutting the pistons - Rarly, can you advise?
