Third gasket worked like a charm!
Ordered header for 4.2 and received 4.2 header with 4.0 gasket. Contacted manufacture and they sent me another gasket. Arrived in large cardboard box, folder over inside of it. Pulled gasket out and found that the fold had caused it to split. Re contacted manufacture and received a gasket that I could use.
