273 guys..Heads up!!!!

They didnt run 3.63 size dia gaskets. the chamber is 3.91 on the head thats where i f#$%ed up & figured id be ok with bore dia gaskets made the ones that were on my motor when i tore it down were 3.91 bore made by fitzjarold (spelled that wrong im sure) i figured thet were aftermarket & ordered smaller. The fitz fire ring was @ the 3.91 not 4.140 like the cometics. see what i mean now?
