Compression help Having issue with my compression on my 370 turbo setup.. I have a fully forged flat top motor with prc stage 2 heads (about10:6 1 ) compression and wating to run about 15 lbs of boost but tuner is having pre ingnition issue.. So looking at options. What old be the best benefits.. E85.. I thought about changing heads to some 317 with 71cc and a thicker head gasket.. To get compression down.. Would like to keep it on 93 octane if possible but will convert to e85..

As of right now no..it's at the tuners and he changed to plugs and put 110 octane gas in it and right now there is no issues at 12lbs. But being a street car can't keep putting in 110 octane in it.. He wants to keep trying things at my expense.. But coming here to the best place to find anything out
