273 Heads, closed chamber

Hey Karl, look at the photo closely, hardened seats? I will need to check.


It's hard to tell in the photo...

I had hardened seats put in mine, and also 360 valves, 1.88" intake and 1.6" exhaust... I put mine on a 318...

I finally found the pictures of mine with hardened seats and the 360 valves....
