You're welcome..... it looks like you're dealing with too high a CR for the usual street setup with the pistons and stroker, along with the smaller combustion chambers of better new heads on the market. If you do want to push the CR a bit, keep in mind that the Edelbrock open chamber versions have 65 cc chambers, and the aluminum will allow you somewhere in the 0.5 to 1 point high CR for approximately the same detonation resistance versus an iron head. The Edelbrocks are pricier, but you can get them on sale from Autozone at some pretty healthy discounts: 20% straight cash discount at times, or even 35 on a gift card that you can use for a new Edelbrock intake and some other stuff.
And you can drop the dynamic CR with the cam selection and some cam timing adjustment to help.
