Hi All

I occasionally contribute help as well as seek it on the V/P and Crusader Section of this forum. I could really use some help with a motor I'm replacing a head gasket on. First off I need to ID it. The engine model number / serial number is : S454SR 33037. I believe this is a Gen 6 454 because it has roller lifters, but I need the engine model year as well as the torque specs for the cylinder heads and intake manifold. The heads are iron oval ports and the intake is iron also. It is a carbed motor. I believe it is a non HO motor due to the oval port heads. Any help will be greatly appreciated.


Thanks
Jon Allen
