I followed the advice here on setting them around .016. The car seemed to be down on power at the nationals. I have only had it out of the garage twice this year since I was working 7 days a week. While at the nationals the car as I said felt down on power. I changed the plugs in it and man was it FAT. I put a timing light on it and some how it had lost 15 degrees of timing. I set it back to 36 total and changed the plugs and finished out the weekend.

So today I finally run the valves. They had loosened up about .010 to .013 on every valve. The plugs had one trip to the track and back and they look FAT still.

Would you change the jets or wait till I drive it since I tightened up the valve lash to .016? They were around .030 and I understand that I lost some lift on the cam which inturn affected the vacuum.

What would you do
