Those look like reverse flow heads. They will not work on a conventional SBC. LT-1 front distrib motors only. You can't use them, but they are not your valve/piston problem..

Here's what I think is going on as the piston is coming up on
Exhuast stroke the lifter is opening as the piston reaches tdc the valve is fully open I don't think this is correct shouldn't the valve be fully open before tdc I think I got a bad cam ??? Any help please an thanks

You do not have the crank gear correctly timed to the cam gear. Take a real close look at the multi position lower gear. Better yet get a gear with only one position.. Problem solved..

Most SBC heads with large valves that I've seen have the intake valves about even with the deck.
Just a thought, are you certain the pistons are installed with the valve reliefs towards the intake manifold? ssmonty

Heads are useless on earlier blocks. This area (Flint) was where they were originally produced and several hundred "escaped" from the factory. I have seen pipe threads tapped into the front of the heads bypassing into the intake manifold. Entire front welded up and then drilled for conventional cooling, etc. All in vain, as the heads overheat internally and won't work.

Did you install new lifters with the cam? Are you sure you are using the correct lifter for the cam (solid vs. hydraulic)? What about pushrod length? Did you install longer pushrods or did you check valve train geometry to get the correct pushrod lengths? I know these questions probably seem elementary but...................

That thing has way too big of an intake valve in it for a 190cc runner..
