The only thing I would question would be whether you would have been better off sticking a wire brush attachment to a drill down the exhaust ports before grinding-in the valves. It's still not too late to do it, just be careful that you don't catch the newly ground valve seats and bog-up your (OK Dapinky's!) previous work.
Thanks for the suggestion Neil. Job just done! Used the wire brush attachment on my drill via the manifold end, then used a dremel to carefully do inside the valve area being careful not to touch the newly ground seating. Then used a compressor to blow the area clean. Also did the same to the exhaust manifold - well, the best I could.
On the same subject, did you spin up each valve (especially the exhaust ones) in a drill to remove the excess carbon deposits?
Again, thanks for the suggestion, I will do this.
BANANA cam cover?!?
Just for you Neil, here is a pic of how the cam will sit within the engine bay when the re-build is complete. I know its not an exact colour match, but I think it's looks pretty good and should be fine when everything is complete. What do you think guys?
