the engine was built years ago, and stored with lotsa marvel mystery oil. put it in the car last year as I was doing work on it, I put break in oil and ran it, it was getting low vacumn 10" I noticed a anti freeze leak coming out the front corner of the left cylinder ( front). the person who built the engine didn't put sealant on the head bolts. I pulled the heads, installed new head gaskets and new arp bolts. while I had the heads off I noticed all the valves on the heads carbon on them except the valves on number 1 cylinder they were spotless. I put everything together and torqued to specs, I then started the car to these problems
