yes how much clearence is there between the valve and piston……. I am wanting to shave my head to the max.. i have a b18c1 with type r cams.. please email me back if you can help in any way it would be appreciated
Your b18c1 with Type R cams already gives you a pretty high compression ratio of 11:1. Shaving the head may result in the valves and piston colliding with each other. However a way around this is to shave off some material from the top of the piston where the valve and piston meet in order to prevent this from happening. This is already going deep into racing territory so if you go this route then I recommend a good book on this subject called Racing Engine Builder’s Handbook by HPbooks.
They go over everything from what I just talked about including milling the head to reach maximum compression ratio. Take note that this may end up making your car undriveable on regular roads.
well do you know how much you can shave one and be safe
I can’t recall but I believe the block or the head has a marker that lets you know how much you can safely mill without it causing problems. For every .10″ removed the compression ratio is raised by .2. After milling you’ll want to check the piston to valve clearance. Before milling the head you should try a thinner head gasket if you haven’t already done so. It should help raise the compression ratio a bit.
