I am after some help-suggestions with spark plugs!! 
SBC 355, 11.1 compression, Brodix heads 2.10/1.6 valves, .660/.630 solid roller, dual tunnel ram w/ 660 center squirters, msd 7al2 ignition 85551 distributor, unable to use cap-a-dapt do to tunnel ram
previous combo I used AR3932 plugs, I went to AR3935 plugs and they are running rich, jetting is 75-73 one number below stock for the 660's. I am aware this is combo is not for idling, but exhaust is very strong and plugs are black, throttle response is quick and fast, secondaries are set up for enguaging at 4,000rpm
plugs are gasket, style 7/8 reach with 5/8 socket
Thanks for any suggestions, I dont wont to toss the tunnel ram
