I just had a call from a buddy here in town, whom I have never talked to before 9am and he says " I woke up in the middle of the night remebering a neighbor that Dad was helping with a 235 and the same thing happened. It was when I was 10, but I remember he built a motor and it ran great the first drive. He parked it and the next day it smoked. Dad ran a torque wrench on ALL of the head bolts and found one that had settled".
I told him that I had put a socket on most of them last night, but will run a torque wrench on ALL of them today at lunch before I by pass the heated intake.

Thanks for all of the suggestions and support!

you know if the head has the lump port mod there are hidden head bolts in the ports.
