Re: What's the deal with the half-a$$ SRT exhaust valves???
If you want to hold the valve open, Just pry the small tang on the spring off the square spring retainer. Rotate the valve full open and reinstall the spring tab. you should have clocked the spring tab to the opposite corner of the square retainer. This will allow the spring to hold the valve open. Be aware that exhaust will drone significantly at 1600-1800 rpm and at 2100-2300 rpm.
