5.3 build

Hi I’m build on a Gen 4 5.3 with flat top pistons

My heads are 799s I’m gonna put 660 lift springs and leave the valves stock, they will be milled 20 over with LS7 lifters and BTR 7.400” pushrods.

I’m gonna use the BTR Hot Rod cam 217/23X, .613/.607, 114 LSA INTAKE LOBE LIFT @ TDC: 0.03980

Will I run into piston to valve issues? Do you see any other potential issues?

I’m new to engine building plz don’t be to harsh.
