I was reading your thread "one off bucket list, valve seats", and i wanted to confirm what size valves you are using with those seats ?
I am thinking about doing a 4 angle valve seat on my 2L head, but with 45mm, 45 degree intake valves.
Either way, can you let me know what results you had with the 4 angle seats ?
I was reading your 73 GTV restoration thread and on post #165 there is a pic where you have the headlights on. The headlights look very bright and i was wondering if you have made any mods to your wiring or bulbs etc as they appears to be very bright?
I just now saw this sorry for the delay. I have not used any such gauge and even if it did show it not to be 90 degrees I don't know how you could change it unless you used a different pilot. I talked to the neway Sales Rep and he didn't mention anything about such a gauge either. I have not found it necessary to use such a gauge. There is a spec for runout and as long as something such as the wax paper from a Hershey's kiss is grabbed by the valve and seat at clock positions around the valve face you're good to go. You can run into trying to chase a absolutely perfect seat and end up grinding the whole seat away. Hope that helps. I might suggest that you call the sales rep at neway, they are very helpful and more than willing to answer any questions you might have.
I was reading your thread "head work" and have a quick question about using the Neway cutters. Perhaps i have been watching too many YouTube videos but i have seen when the Neway Pilot is installed in the Valve Guide, an instrument called a "concentricity gauge" is used to ensure the pilot is sitting correctly, at 90 degrees with the valve seat to ensure an even cut on the valve seat.
Could you please let me know if you have used any tools to ensure the Neway Pilot is inline with the valve guide or at 90 degrees with the Valve seat? or are the Neway tools that accurate that there is no need to check the allignment.
Thanks in advance.
