422 dyno fail

All 4 corners of the header bolts on early small blocks are wet holes but I do know RTV was used on the bolts. I also thought about this….it was so humid in that dyno shop the floor had standing water on it. The relative humidity was high enough to cause rust on any motor sitting out for a week. The headers had obvious signs of exhaust leaks as well. I am confident Jack will figure this out and I have no problem paying him for his time and knowledge.
