early 80's 350
im not familiar with the Chevrolet side of motors. i have it in my boat and it is a engine out of a suburban that i rebuilt and had it bored to a 383. I'm getting water on top of the pistons on #1 & 7 cylinders. just built the motor and on the test stand everything checked out. put it in the boat and it runs shitty. the head doesn't have dowel pins they look to be filled or either broke off and machined smooth. could i have missed a plug or something and causing water intrusion? idk how it could be a head gasket and i hope it isn't a cracked or warped head. thx for any input guys. the compression is around 160 on all cylinders and there is enough water that when i pull the sparkplug out i can pour the water outta the plug. i took the hoses off the risers on the port side and run it trying to eliminate the riser malfunctioning and still got water in the plugs. i removed the heads and took these picture. the picture with the studs in backwards is to show the placement of the gasket and all the open holes. also when i was taking the heads off alot of water went all over all the pistons but the sludge that you see is after i wiped the pistons off a little bit so im assuming that all the cylinders arent running correctly. any ideas?
