I am putting together a CVO based 103 (HD 103 stroker kit) in a RK. From my last post regarding piston to valve running clearances I have now skimmed 40 thou from the CVO 103 heads as suggested by hdm88. Whilst the engine is in bits would it be beneficial to change out the stock CVO253 for an alternative cam i.e. 37g. Is this cam suitable for a 103 displacment, are there any others I should consider, I would like to have a build which is torque orientated.
