aar0sc Posted April 7, 2014 Share Posted April 7, 2014 Need to change my Spit's head gasket, the engine is "DH60***HE" (can't remember the number in between). This is my spare headgasket: Will it fit?Thanks, Aa Quote Link to comment Share on other sites More sharing options...
oscarthedog Posted April 7, 2014 Share Posted April 7, 2014 hi, the label says S1500 (spitfire 1500). if yours is a 1500 engine then yes it should fit. Quote Link to comment Share on other sites More sharing options...
Nick Jones Posted April 7, 2014 Share Posted April 7, 2014 That gasket has the tab on the back indicating that it is for a recessed block. Your Spit is very likely to have this (engine number suggest Dolomite origins but no matter). The tab on the existing gasket should be visible if present and will confirm it.Nick Quote Link to comment Share on other sites More sharing options...
aar0sc Posted April 8, 2014 Author Share Posted April 8, 2014 Ah! So if there's already a tab, it takes a tabbed gasket, and if not it doesn't - are there just two basic Spitfire gaskets then? Quote Link to comment Share on other sites More sharing options...
Dannyb Posted April 8, 2014 Share Posted April 8, 2014 That's right . recessed and non recessed. Quote Link to comment Share on other sites More sharing options...

Pete Lewis Posted April 9, 2014 Share Posted April 9, 2014 Aaron, the recess spoken about is in the block , just a small counter bore in the block face around the periphery of bore, this design is supposed to help support the gasket fire rings .so if present you have the tabbed gasket at the rear end suggest you check all the head nuts and washers for any deformation, as this soon looses torque as the washers collapse and you get blow by across the head faces as the gasket is not clamped adequately.Pete Quote Link to comment Share on other sites More sharing options...
aar0sc Posted April 10, 2014 Author Share Posted April 10, 2014 Thanks Pete, they all look normal! I found an old-school engine shop, who skimmed the slightly bowed head for me:Nice and shiny now!Lapped the valves in, had a lovely time doing it under the watchful eye of my mate James, and it all went swimmingly until we found a crack in the exhaust port of the 4th (Rearmost) cylinder... :( Decided that we may as well go on with it, as it'll still be far better than how it was, but I will speed up my planned replacement engine (Whose valves are now in this head, as quite a few of the 1300's valves were cracked).

Pete Lewis Posted April 11, 2014 Share Posted April 11, 2014 think about ...........nows the time to add some exhaust inserts , as for lapping valves in I use a good squirt of oil on the stem,. a good dollop of paste on the seating and connect the battery drill to the stem and open /shut/ fwd /reverse the operation .till a nice dull seating .but a cracked seat will not last long Pete Quote Link to comment Share on other sites More sharing options...

Pete Lewis Posted April 14, 2014 Share Posted April 14, 2014 Sorry we didnt have too much chat time, but its reassuring to see younger drivers engaged in the classic scene especially when the insurance schemes have made it hopeless to get reasonable insurance costs due to idots and go faster old,moderns contaminating thethe claim statistics for 'proper classic' keep it up youll soon have the Spitty back on the road Pete Quote Link to comment Share on other sites More sharing options...
