What you do need is new springs, carefully fitted, and make sure you open valves with piston at TDC, so you can be sure you have enough valve-piston clearance. k

Easiest way to see what there is which will help as I was planning on skimming the head to reduce the combustion chamber capacity so checking how much clearance I have before doing the machining will stop me carving off too much. Should be OK though because the duration is only 4? more than stock. Yes I know I could start with a 1600 head but it's cheaper to skim a 2l injection head down than to cut bigger valve seats, do porting and also convert to unleaded. Not wanting a street stormer but just something with a little more flexibility. Yeah I know I could just go buy a 2L lump and have done but it's also to give me something to do over winter. The current engine is running OK so I've got time to do this. -- Conor I'm really a nice guy. If I had friends, they would tell you.
