first if you are running roller tip rockers go to the B3racingengines website and read all 4 tech articles
Lunati is a voodoo? check the lobes against lobes in their master lobe list
forget the lsa
where do you want your intake to close with your compression and gas
pick your other valve events and overlap requirements
LCA is a result- not an input but does indicate if you are on the right track
Those heads may require less timing than others and for sure less than stock - ask the questions what others are running
do you have cranking compression?
did you try to retard 4 degrees and see what happens (same as a bigger cam as far as intake close goes) does ping go away- if it does not then intake close difference may not solve your problem
you might try the .028 Mr gasket head gaskets- sometimes thinner helps
what yr says sometimes it's power brakes or bad headers/ exhaust
I take it you already own the roller tip rockers however at .525 lift Iron rockers work just fine
you could use more lift with those heads but you have already made the big jump
remember 106 or 108 would make the pingingworse if dynamic compression is the problem (with the same cam lobe)
take good notes and plot your timing
