Hey Kochic......Been there done that....First things first. Take one valve and hold it on the seat with your finger. Place a dab of grease on top of the valve stem. Now put a shim on the grease (2.00 is good) and install the lifter bucket. Now put the cam in place with the lobe facing away and see how much clearance you have. Find out what size shim is needed to obtain the correct clearance.
To test keeper to retainer fit, I always take one valve (in your hand) and drop the retainer over the stem, put keepers in place and pull up hard on the retainer. It should wedge firmly into place on the valve. If it does not do this, the taper is wrong. Now put the shim size you found above^^ into the retainer and test for fit. It must sit on the valve stem only and stick up slightly above the top of the retainer.
Post results and I will try to help.........Billy

Yes. Everything fits correctly. Our retainer has .070" from top of the valve to top of the retasiner. Check that on the 650. You would want .090 max.
