Who ground the cam, Jones?
The heads as 2.02 versions from the factory are decent factory performance heads. You can go to see stock class nhra demons and dusters and find them in the high 10's to low 11's "in dedicated race cars", big difference there, but my point is made.The heads do 225-228 cfm by .500 lift as factory versions. If they just got 2.02 valves as an upgrade, they don't do as well in flow as the steeper throat cut from the factory does.imo
In the end they are not a race head, just a factory performance head for their street fighting sb v8's in The late 60's early 70's. They have been modified by countless people to race/compete with success, including myself, but there are much easier or faster to configure heads out there to use. I would port them a little, just to 255 cfm, 'doesnt take much' before i bolted them on to anything warmed up. Just spending 2-3 minutes an intake port "in the right hands" would have them around 240 cfm... The cam will use them up in their current form, good choice. Should be run good.
