Hello all, Hagerty member and first time poster here with a question for the masses: I recently bought a '57 Canadian Pontiac 261 that I was planning on rebuilding. After pulling the head, I found two blown cylinders (likely from not drilling the steam holes in the 235 head). When is it worth having a block sleeved?
