following the breakage of a cam sprocket I have to replace the heads. Heads have been refurb, skimmed etc and turn over perfectly on the bench. the bottom also turns freely. When the heads are refitted with thickest gasket, they appear to foul the piston and cannot be turned. At this point the cam belt is not fitted but when fitted and timed up same problem. Lost how to resolve this. Any ideas, suggestions very welcome. Thanks. Peter
