clearence ? LPE219 and Pro toplines

I'm putting together a LPE 219 cam with 190 Pro Topline heads with 1.6 RR on a 1992 350 TPI motor. Is there any clearence or fit concerns with this combo (pushrods, valve covers, etc)? The heads have 64cc, and I was wondering how can I get about 10.1 compression.

To get 10:1 Compression you need some Flat Top Pistons with 4 reliefs and a .04 Quench.

There isn't any way to get a 10:1 without changing pistons, or decking your block and using a thin gasket that makes your quench way too tight.
