Hey, I was just wondering if the gn's are suppose to have exhaust valve seats or not? I got a kit that didn't include exhaust valve seals. And also, have anyone had any luck with a .020 crank? I smoked all my .010 cranks so now it's time to turn them to .020. It's going to be street/strip car. but mostly street.
The GM shop manual says no seals on the exhaust valves of a non-turbo but I am not sure but I would think it would be the same.
Yep, no seals on the exhaust side...
