What can I gap my spark plugs at?
 

Hello guys I have a 350 chevy with 9:6 to 1 compressin, Dart Iron heads 200cc ported, quick fuel 650 mech secondary, comp big thumpr roller cam, Hei with 50 volt coil and high performance springs and weights with vaccum secondary. I currently have my plugs gapped about .040 can I go bigger on gap and will it help me to burn my fuel better? Thanks

try .045
Im using .050 on my MSD system with no problems
but what you need to do is read the plugs.
they will tell you what you need to do.
