I got an email this morning and here's how it went:

Hello Henry,
Sorry to bother you but I just wanted to see if your preferred sealant used between the heads and cam housing is still Threebond 1184 or now the Durko HT?
Thank you for your help and Happy Holidays,

Good morning XXXXXXX
No bother at all.
Either product is good for this application.
We used ThreeBond for 2 decades+ with good results.
At the prompting of a sales rep we decided to do some comparative testing between
TB 1184, Dirko Grey and Dirko Grey HT. Our test results were very close.
Break away, squeeze out, rotational flexibility and chemical resistance were the test criteria.
The clear winner was Dirko HT based primarily on the break away and high heat range resistance
In house we use Dirko HT but we offer the choice of HT or TB in our sealant kit.

Cheers
Henry
