As far as I know Rev, the power valves I've been using are good. New out out the box from Holley. And the valve seats too. Dknght, the 2nd's are open just a little at idle. I did that the last time I had it apart. My cam is 240* @.050 with .540 lift big but not that big. So if you got that 289 going with that size cam I should be able to figure this one out. I'll finally get some free time this weekend to tyr all of your suggestions and get it tested with a new vac gauge. I'll let ya know how it turns out . Thanks
