P38A Gems compression results

Hi all,
I would like a second opinion on these compression results for a test on a v8 gems.
They show just acceptable but when I work the p38 past anything more than comfortable she throws a wobbly with the cooling, dumping fluid out the overflow pipe.
System is still a bit pressurised after 12 hours.
Im thinking nos 8 or 1 are pressurising cooling system through gasket or liners may have slipped, if its lined at all.
Following a hard motorway stint yesterday it boiled all the coolant, no fluid, just steam left in it.
Theres no water in exhaust gasses.
Does this point to anything specific with the landyzone fonts of knowledge.

Pull those heads this is what I found after chasing coolant leaks for a long time and pressurised cooling system on my 4.6 Thor

That was a really nice bus stop and bench in that picture..

Im hoping the knackered gasket is what I find... As you did.

Did snif test said all was good I had UV dye in the coolant did an oil change and found my oil engine glowing under the UV light

A picture says a thousand words. Thanks btd
I hope I have the same problem on my 4.0
