Thanks everyone for posting. Steve, the FI bosses appear to be the same diameter just two separate instead of a single boss for two injectors. The small raised circles on the bottom of the runners look nothing like the FI bosses.
I ordered a couple intakes this black Friday. Both sets of heads from last year's sale checked out fine which lead to another purchase this year. I am sure if these heads were coming apart when used we would hear it six ways from Sunday even on the ready-to-run versions. So far guys are happy with SM.
I might pull the trigger on the main caps just yet. Feel free to update the thread if you are happy or unhappy with what you ordered.
BG you keep on keeping on
