Damn, now your talking! Nice grind, I may just use that in my 360 LA hydraulic roller block. I’ve not seen any mention of what rockers he’s using yet, but I have the feeling he may be needing to upgrade to adjustable rockers to meet his goals. If you stay hydraulic flat tappet, Howards has a good .904 specific grind for the lift range of your heads, so while the heads are getting worked, get them set up with a 98434 K (I think-32 or -34) kit with 4 groove locks (if you’re using your old valves)

This cam has 277/283 advertised duration, and is in the sweet spot for lightly modified J heads.
