Solid roller cam Vs Hyd flat tappet

So I have an engine I been building since last summer haven’t been able to be as consistent as I want with it with everything I have going on it’s a 89 360 block with KB107.060 pistons stock rods/crank bought a set of trick flow heads
(TFS-6141T784-C00) and installed only after I installed them I realized I bought the ones set up for solid roller cams. I originally wanted to put the hyd flat tappet set up I had from my previous engine and I know all I’d need to do is swap the valve springs to do that set up but it sounds like the solid roller set up might be the better way to go and I’d be able to get a bigger cam with that set up. Just wanted to see what you guys thought of this new to the engine building/ mopar world So any help or criticism would be greatly appreciated.
