I Have a obd1 JDM B16a with ctr cams and upgraded valve springs and retainers. i/h/e milled face.030 and spoon 2 layer high compression head gasket. I was wondering what would be the highest i could rev to without any major threat to my engine, while still making power. My stock setup is at 8200 i believe, but since i have upgraded my cams/valvetrain can i now rev higher? around the same as a type r?

 

8.5 max cuz ctr cams dont make power past that
