All heads flowed on the same flowbench (I
forget the model# but its a fancy all digital
one) at 28".

The exhaust ports have a little TIG welding
(not reconstructive surgery). Valve sizes
on Green Monster was 1.84/1.56. Valve sizes
on these supersplits were 1.96/1.55.
(Stock is 1.86/1.45)

Holy exhaust port!!!!

Who was it that said these heads are exhaust weak?

Is there a FAQ about how to read this? I'm completely lost. (I don't know much about heads anyway)

Are those numbers in CFM?

 

good im not the only one lol
