Default Is there a downside in using -29 dome pistons?

I have 64 or 65cc combustion chambers on my heads and according to JE pistons' website I would need -29 dish pistons to get to around 9.5:1 compression. Is there a down side to running deep dish pistons? Are they weaker or more prone to detonation? Thanks

Do they even do them with such a large dish ?

The hassle on an LS is having room for the dish, due to the pin height being quite high in the piston
You might only get it with stock stroke.

I wouldnt have any concerns other than that
