HK450GT, 4 blade rotor, phasing issue

I am rebuilding my HK450 to run with Flymentor and a 4 blade head to go in a MD500. As a test bed I am using a Titan 450 to test the setup.
I have yet to spin this unit up as I wanted to concentrate on blade balance and weight, I have all blades within 0.02mg and all balance to the same point. My next issue was phasing, simple process once explained, but my HK 4 blade rotor will not phase to the recommended 90degree, because of the location and size of the swash retainer I can only get 85 degree.
Does anyone see an issue with this or do I have a faulty 4 blade head.
