The old Payen style lasted 30 or more years until I did a valve job 4 years ago. The Cometic lasted 4 years until it failed. I?ve discovered some extenuating circumstances which may have caused my failure but I am interested in the responses, especially from those who have moved up to the 89 mm liners. How have you sealed the 89?s and or is it too early to report results? Also please indicate if you?ve milled the head and by how much.<br><br>I?ve discussed this with some very reputable Triumph performance folks in the last week and gotten some good input but would like to broaden the discussion. Once we see some responses I?ll be pleased to share what I?ve discovered. Those who I?ve already discussed this with can chime in or not, I will include your advice but not who you are unless I have your permission.

I'm not sure about the 4A but suspect it's got cylinder liners. The real trick--ask me how I know!--is making sure the liners stand proud by .003 or close all the way around the cylinder. As I'm sure you already know, cinch the liners into the new figure 8 gaskets using the head bolts and sockets until you get them right. List advice has always seemed to be that copper compressible gaskets serve better for a long-term seal than steel. ISTR that Payen was recommended as best, but am not sure it's available anymore. My current head gasket is from TRF and is holding up extremely well, after all prep was meticulously done. Then again, I don't rev the engine over 4k despite my driving has historically been "spirited." Others on the List are certainly more qualified than I, so hope they respond too.<br>Terry Smith, '59 TR3A<br>New Hamsphire<br><br><br>> On September 20, 2017 at 1:51 PM <a href="mailto:asg123@centurylink.net">asg123@centurylink.net</a> wrote:<br>> <br>> I have asked a similar question before but my mechanic and I are still undecided which rabbit hole to enter<br>> Does anyone have experience with which head gaskets hold up best against blowing out around the combustion chambers?
