Single plane vs dual plane intake

You’d be surprised!
I sold almost all my stock headed intakes and I still have 5 stock headed intakes, less than half of what I sold, 8 W series intakes.
Yup! I love to tinker. I swap them out and actually use them before I give an opinion about them. Same with cams, same with heads.
You have way more ambition than I do. Sounds like a interesting nitch to the hobby though.
