Frankly, I don't know for sure. I think the no lead exhaust valves are stainless. You might try pulling the valve cover and seeing if the exhaust valves are magnetic. If they are, they're probably steel, and therefore designed for leaded fuel.
What kind of shape is the rest of the car in?

Is there any way that I can tell if the valve seat hardening has already been done? -----Original Message----- From: Bill Gingerich [mailto:[EMAIL PROTECTED] Sent: Monday, August 04, 2008 5:46 PM To: 'Daniel Parrott'; [email protected] Subject: RE: [Spits] GT-6 MK3 in Georgia Dan, As I recall, they were designed for leaded fuel. What my son did with his '72 GT6 was to use a lead substitute that he bought at his local auto parts store. When you're ready to pull the head, you can have the valve seats and valves redone for unleaded fuel. I did that with my '74 Spitfire. Not a problem.

It's been a while, but do they require leaded gas to run? If so, how do the listers cope with that requirement? _______________________________________________ Support Team.Net http://www.team.net/donate.html [email protected] http://autox.team.net/mailman/listinfo/spitfires http://www.team.net/archive
