what are the OAL of these plugs?
how many spark plugs in a box?
I forgot to ask, will this plug run hot enough for a 9.1 to 10.1 compression?
I have a 350 Chevy block with iron vortec heads. also, running the 30226 ez-fast 4 port EFI, and an HEI Distributor. Header clearance is an issue, so I need a short plug. Can these be gapped to .045 in?
