Doing great job so far.
For the most part, these gaskets are perfect. I do however, think that Harley's rocker box gaskets are better quality. That is the only thing I would do different.
Great set of gaskets. Way better than the JP generics. Don't cheap out and just spend a few extra clams. You wont regret it.
