What can anyone tell me about cylinder heads for -
- a - turbo motors - as used by most people on the forum
- b - non-turbo (naturally aspirated) as used on NASCAR and Indy Lights engines?
I assume "b" heads have smaller combustion chambers for higher compression - were they just milled or were they different castings? What about valve sizes, port sizes or other differences? And how to recognize them if buying them.
Thx - Derek
