Vortec 350 with flat top pistons???

Hey guys need some help. I am building a 98 vortec 350 for my camaro. I have a set of new flat top pistons(old style) I want to put them in my engine but my buddy says that the VORTEC will have too much compression with the vortec heads to run it on the street. I don't want to bench race him on this issue without some ammo. Has anyone ever built an engine like this with flat tops and stock vortec heads for the street? he claims it will spark knock all the time. Oh yeah, it will be fuel injected using factory set up.
