How would these do on a hydraulic roller, street motor (RHS 502)

With a 4.2" bore and a 4.5" stroke your going to need a fairly stout head that can flow some serious air. 447cfm @ .700 lift will get it done. What are your goals? 800-900 hp on the motor? For a bore that big and a stroke that long there are only a couple heads that will work, mozez are one.

I am using them on a 450" small block on alcohol with a pro-mag 44 ignition. These heads have made 2500+hp in forced induction applications.

I'm sure you've already done it but put these on yellow bullet . Will be a bigger demand for this type of head on there . Good luck !!!!!!
