AarhusTr6 Posted December 21, 2020 Report Share Posted December 21, 2020 Hi all My cylinder head is with Peter Burgess undergoing surgery! The guru (Peter) recommended Payen black composite are the best for gaskets, and I guess I should get a complete gasket kit, but the only full kit I can find is in the US https://mossmotors.com/head-gasket-set-payen-brand-7 Budget withstanding, can someone guide me to sourcing what Peter suggests from the cylinder head rebuild?

John L Posted December 21, 2020 Report Share Posted December 21, 2020 (edited) There are 2 gaskets types for the blocks, check the block to see if it is recessed around the top edge of the bores, or the surface is flat at the top of the cylinder bores. This is a recessed set from Rimmers Head Gasket Set - Recessed Top Block - Payen - AJM1193PAYEN (rimmerbros.com) John Edited December 21, 2020 by John L Quote Link to post Share on other sites
AarhusTr6 Posted December 22, 2020 Author Report Share Posted December 22, 2020 Hi John Thanks, what difference does it make if it recessed around the top edge of the bores, or the surface is flat at the top of the cylinder bores - and how does this affect with gasket I get? thanks Richard Quote Link to post Share on other sites
John L Posted December 22, 2020 Report Share Posted December 22, 2020 Its a different gasket for each of the different blocks, I expect for a recessed block, the fire ring in the gasket is bigger to give a better sealing area, could Peter Burgess not supply/get a gasket for you? I thought also you had a PI engine the gaskets kits from the USA may be for carb engines and the manifold gasket may be different also. John Quote Link to post Share on other sites
AarhusTr6 Posted December 22, 2020 Author Report Share Posted December 22, 2020 Hi Its a CF engine so am 99% sure its recessed, but I have mailed Peter. Richard Quote Link to post Share on other sites

Richard The recessed gasket has to be used on the counter bored block as it has extra fire rings in it to full the gap generated by the counter bore. This design was used on formula 1 cars to the day. The TR6 Block flexes and the later the Block flexes less, due to a rib (web) being added to the block casting. For the Bottom End gasket set go to Ferrari Piston Services as they are the main Distributor for Payen here in the UK. You would have to buy from one of their outlets! Sorry I do not know the Payen part nos. for a carb engine. Bruce (ex Payen -Coopers Employee) Quote Link to post Share on other sites
AarhusTr6 Posted December 23, 2020 Author Report Share Posted December 23, 2020 Rather embarrassed to say I asked Peter and he replied - - you need to check the block . not the head! I will take a picture when I go to the man-cave today Richard Quote Link to post Share on other sites
AarhusTr6 Posted December 23, 2020 Author Report Share Posted December 23, 2020 Hi There is a definite lip around the edge of the piston bore Quote Link to post Share on other sites
John L Posted December 23, 2020 Report Share Posted December 23, 2020 (edited) That is a recessed block, so you need a recessed gasket. Your old gasket should have a tab at the rear of the gasket to identify it, a small oblong piece of gasket that sticks out at the rear.

dingle Posted December 26, 2020 Report Share Posted December 26, 2020 Just to muddy the waters, the recessed type block was not fitted on 71 carb cars. The engine is probably not the original. Also, make sure that the manifold gasket is the appropriate for the cylinder head. 1971 and earlier carb cars had a log type intake manifold and the spacing between the intake ports was .640" and commonly referred to as "narrow port heads" 1972 and later carb cars had intake manifolds that were shaped to flow better and had wider spacing (.840") and were known as (wide port heads". The manifolds are shown in Rimmer and Moss catalogs. It is important that the gasket matches the head&maniforld. Either type of manifold&head can be fitted to either type of block.

Hi The car is a 71 but its a later engine, assume manifold etc is all from later engine too. Quote Link to post Share on other sites
