Even though I feel the RPM intake is the best for this combo, the TM6 would be my second choice. Pretty hard to find though now a days.

Sounds like the consensus on my potential performance gains from the head work is 2 to 4 tenths. I’m hoping to hit the higher end of that range, obviously. I’ll report back when it’s back together on what the “butt-dyno” says, but real data won’t be available until the rain stops, which could be a while.

Thanks to all for the input and conversation.

Good luck with your new updates

Seems like the answer is in his sig? Looks like he knocked off couple tenths.
