Radiator under constant pressure?

[Herbie Null]

I had this problem once, mine was a aluminum head on steel block with a single layer head gasket. I chased the problem all season, water was not getting in oil or coming out of exhaust so I just left the pressure lever up on the radiator cap. When the engine was torn down the head had warped some, resurfaced head and used Cometic MLS gasket and never had anymore issues. I do believe the MLS gasket would have fixed it. I dont know if you have aluminum head are not, just passing along what I came across.

I don't have aluminum heads, but now that you brought up warpage I did have a hard time finding heads that were not warped so bad and can be used. These head are about..008 warped but the cc's were high enough I was able to cut warpage out and get to correct cc. I had a couple heads that were. 025 warped and could not use. I wonder if these have warped. This will be at bottom of last to check after I finish healing and checking the basics first
