Storydude1 Posted May 21, 2012 Share Posted May 21, 2012 Did Valves on DesertFind today. I'll let the numbers speak for themselves. Spec is .010 intake, .014 exhaust. Pass side #1 and 3. #1 intake .029 #1 Exhaust .030 #3 intake .031 #3 exhaust .029 Drivers 2-4 2 intake .030 2 exhaust...040 4 intake .026 4 exhaust .029 1980 EA71 motor. 121K. I can safely assume they have NEVER been done. It IS much quieter and actually has some power now. Quote Link to comment Share on other sites More sharing options...
Hatchback Lou Posted May 22, 2012 Share Posted May 22, 2012 My '84 was the same way, couldn't believe it. Those EA's just want to go, to hell with specifications! Quote Link to comment Share on other sites More sharing options...

Even with valves that far out, I made a 320 mile trip this weekend, over some 6K ft climbs and knocked down 34.8MPG @70ish. Quote Link to comment Share on other sites More sharing options...
