Thanks, John. Martin Tagliavini and I have been emailing. I've requested technical specs and he is working to get me information. Both intake
and exhaust guides from them are the same length where Ferrari intake guides are 2.9 mm longer than exhaust IIRC. So, I've quested that along with the hardness depth of the valves as the tips may need to be ground to maintain the length after dressing the seats.
I know we talked about this but I was reading the WSM and it states that if the clearance between valve stem tip and cam lobe root diameter is less then the minimum spec then the seats should be changed.
If you are going to tell someone how to remove a bolt you should at least know which way to turn the wrench.
