Articles Austin Healey • MG • Triumph • Jaquar The Stag Heads Come Off By Richard Truett AST fall I bought a 1973 Triumph Stag that had been stored in an Indiana barn since 1987. I got the engine running barely well enough to propel the Stag into my warm garage for the winter. My plan was to have the car roadworthy by spring. I performed a compression test and found 7 of the 8 cylinders were all within 125-140 pounds. But one was a disappointing 105 pounds. That meant the heads were coming off. Exec no recoil cfg for cs.

And you know what that means when you are dealing with any version of the Triumph overhead-cam engine: There’s a good chance a stud or bolt will break, leaving you to deal with the frustrating nightmare that goes along with that. But I got lucky. Using the special stud removal tool you buy from Stag specialists, I was able to remove the heads with no trouble. I saw a thick crust of black carbon on the piston crowns and combustion chambers, but nothing structurally wrong. So, I took the heads over to my local machine shop -- the same one that built my TR7 Sprint engine a few years ago. -- I wanted the heads checked for straightness, cleaned and the valves inspected. A week later came the call you dread when you own a Stag.
Truett, you need to come down here and have a look at these heads. I can’t really explain what’s wrong over the phone, you just really need to come here and see it.” My heart sank. This didn’t sound good.
When I saw the Stag’s heads, all cleaned of carbon, I couldn’t believe my eyes. Chunks of metal were missing from the combustion chambers. During the long storage, moisture eroded the aluminum and left deep pits in the metal.
One of the valve seats looked ready to fall out because there was so little aluminum around it. On the gasket face or deck of the heads, more metal was missing where moisture had eaten it away. The shop recommended I buy a good used set of heads. Dahej serial wikipedia.
But that’s no easy thing with a Stag. With a total production run of around 26,000 Stags and only around 2,400 ever sent to the United States, these unique cylinder heads aren’t exactly common. And when a good pair does become available on eBay or elsewhere, they don’t go cheap. Now I understand why so many Stags have Rover, Ford, Chevrolet and other engines under their stylish bonnets.
