Im narrowing down cylinder head selection for my 9:1 N/A engines. I have mild Crower solid rollers and currently 345 Merlins with Dart intakes and 1050 Dominators. Has anyone had any experience with the dart 330 cnc?

Give JimV (Valako Race Heads) a call. He knows Merlin and Dart heads and can answer all your question.

what cubic inch do you have? boat i rigged this year with 548's and dart cnc aluminums made just about 700 hp. he gained about 70hp with a cam change and cnc heads over the previous rhs 320 heads.

I have 540s.

i think you will be happy with them. we were pretty impressed with the power they made
