Very common on high mileage cars, Dunc, Rob, me, Daz, and a few other have had HG changed.
I think early symptom if high temps on track on hot days first.
Get compression test asap (cylinders 5/6 will be worse) to rule it out before you start, like I did, rafting around with stats, rads, water, fans, oil coolers,
My car used to do hot days with a/c running no temp issues the slowly on hot days on track it started creeping up. Since HG changed no issues

Well like I said i did fear the worst and so got the compression test done this morning - results are as follows (bare in mind the engine was not red hot so readings are a little low across the board)
1 - 149
2 - 154
3 - 155
4 - 157
5 - 159
6 - 151
So whilst I appreciate what your saying I wouldn't have thought the above results would suggest a HG?
Any other thoughts?
Also whilst doing the compression check we couldn't help notice the pollen filter had not been replaced for a very long time... but it's just had an Inspection 2
