You need a NGK TR5, Autolite 103 or AC Delco MR43LTS. Sorry, we do not stock any of these plugs.

The difference between the TR4 and TR5 plugs are the heat range. Personally I would recommend spark plug 9103526 which is a 7 heat range and in my opinion is much better suited to your 602 engine in a racing application.
