I like the way this adds up and was wondering which gasket I would use of I go this route? Will I use the LT4 race gasket pn 12367777 now that it will fit like the LT4?

Yes, when the LT4 is fully hogged out by Lloyd for LT4 heads, you use the LT4 Race Gasket.

Injuneer, Thanks for taking the time to measure you intake. I really appreciate it.

Fastbird, I was assuming that and thanks for verifying. I feel better about leaning towards sending him my intake.
