Woolfenden Posted January 4, 2022 Author Report Share Posted January 4, 2022 Yes , but why did they fit them to later heads. Or have I been given the wrong information. I notice in the head gasket sets for later tr6 etc they come with o rings. Hence my question , Hate to put it together and some clever dickie, Harry Enfield comes to mind, you don't want to do it like that? Quote Link to post Share on other sites

Where did you get the gasket set from as normal sets dont have them? Stuart. Edited January 4, 2022 by stuart Quote Link to post Share on other sites
Woolfenden Posted January 4, 2022 Author Report Share Posted January 4, 2022 Thank you for that, something I don't need to worry about. I've seen them advertised by one of the main suppliers, with gasket set and on there own. Jeff Quote Link to post Share on other sites
Andy Moltu Posted January 14, 2022 Report Share Posted January 14, 2022 The 6 pots did not have seals fitted from new. Some have tried fitting O rings as used on some of the BMJ cars. Limited effect. Witor sells bronze guides with a groove to retain a proper seal on the inlets. Work well. Are they needed? If you fit an external rocker feed - probably as this puts a lot of oil up to the top end. If you fit standard guides with no additional rocker feed then no. Quote Link to post Share on other sites
