Street Triple Cylinder Head Compatibility
There's some info on compatibility between heads from daytonas and street triples but I haven't found any between different years for STs.
I have a 2010 ST with a bad cylinder head and I'm looking at a 2013 675 ST head. Both use the spring CCT but I know 2013 was a year of change for the ST.
Are these heads compatible? When did the exhaust ports become oval? Did the cam profile change?
