To make it perfect you need longer valves or you need to lower the rocker shaft. Neither of those fixes is very simple. Lash caps will help but they add another part to the mix and you will most likely need to change pushrods.

Setting up a BB Mopar to have "perfect" valvetrain geometry is no picnic.

Flip thru the valvetrain chapter in my big block book. I show a bunch of examples and some fixes.

The best fix is to buy rocker arms which are the correct length for the application. Some rocker arms are really short, others are too long.
