dbtravis Posted May 30, 2007 Share Posted May 30, 2007 Now that things are going well with my 1920 DB touring, I've noticed that the head gasket weeps a little bit and looks pretty old, so I have purchased a new comp head gasket to install. My question is: As long as I have the head off the car, is there any reason that I should have the head "shaved" or machined? I've heard that you can get a little bit higher compression this way which will lead to a little more power, as well as assuring that you have a smooth surface for mounting. Is there any truth to this? Is there any benefit to this? If so, how much should they take off?Thanks - Travis Link to comment Share on other sites More sharing options...
nearchoclatetown Posted May 30, 2007 Share Posted May 30, 2007 If it only weeps a LITTLE why change it? I'd wait for a valve job and do it at the same time. Mine turned into all new studs, a carb rebuild, cleaning and painting the engine, painting the splash shields,painting the firewall,the radiator,etc., etc. Link to comment Share on other sites More sharing options...
Rusty_OToole Posted May 30, 2007 Share Posted May 30, 2007 You might try retorqueing the head bolts, sometimes they work loose.A machine shop will check your head with a straight edge. They lay the straight edge on the head and try to pass a .003 feeler gauge under it. If the head is true there will be no room. If the head is warped they can true it up for you.It is quite possible to increase power by milling the head. But, at this stage of the game it's hardly worth the bother. Your engine will last longer if you don't monkey with it. Link to comment Share on other sites More sharing options...
