I’d look at something like a MP 296/.557 or equal like cam since your running J heads.
If there not already ported, make sure when the are you have the springs needed for the intended cam to be used.
And make sure the Head porter knows you need to have the lift clearance. iE; Wha cam your using.
Also, if not already done, I would consider moving to a 1.6 rocker (with the MP shaft for almost .600 lift.) on the fully ported heads to get some air and fuel moving. Once you start Devi get that thing up she’ll wanna really go nicely for you.
This set up should be able to bet you into the 11’s just fine.
Well tuned engine, shifting like a demon on a mission, chassis worked out... yea, your in!
