Ha Ha Paul....cheers bud....the head mod I was going to do started to take shape a couple of days ago......this is a couple of extra drainage channels for oil that gets trapped in the camshaft covers especially at high rpm and acceleration.
What I have done is drill a 7mm hole in some core plugs at the back of the cylinder head and then turned down some brass tubing to create a flange and some barbs for fitting rubber pipes.....these fit nicely into the drilled holes with some o rings for sealing,...... pressure to seal is applied with some made up aluminium plates bolted on,
I placed some kitchen roll inside the cam covers to stop any swarf from migrating anywhere, when I finished I moved a neodymium magnet inside near the freshly drilled hole and it did a good job of collecting all the swarf on the inside

ally plates made up to apply sealing pressure on o rings behind brass flanges of drain outlets
