CU29head That is not a 292,probably 261 unless I am seeing things. Waas going to comment if 292 very important not to overheat,will crack it. Good chance of overheating in a towing situation. Used those trucks for real in another life,great equiipment easy to work on. Listen to others on your brakes,good luck ! I'm wrong is 292 ,if you shave your head may have to shave manifold side too,they warp like a chunk of firewood !!
