Reality of manufacturing today is you have to compromise. I wanted to make a true 9.5-1 comp easy to get to.(pump gas) Some blocks are a bit short on deck height therefore the 1.920 comp distance. Valve notches are one item that was missing from the old standard sealed power/trw slugs.Must folks want that so they are included.I can not make every combo at this price.Overall I believe I chose the best options.The set up for comp can be tuned in with deck height and cyl hd cc's.Thanks for your interest.


Btw if anyone is interested just email me or message me here on Moparts
