So valve seat cutting did not go exactly as planned....so just like everything else.
I decided to start on intake casue there were way less to cut, just the 2 from the smashed chamber and 3 more where I replace wonky looking guides and it was the wonky guides that seemed to cause the issue. ! head only needed 1 seat cut so thats where I started and had to cut about 30 off to clean it up because the best I can tell the wonky looking guided was just what it appeared and the center hole was angled. When I cut the seats I put a 5mm pin in the guide and indicate it true at about the seat position so a slight wrong angle somewhere can't result in a valve that doesn't sit on its seat. Then I replace the guide with a straight one which shifted the hole location a few thou and BAM, it can't be cleaned up without really sinking the valve and will need to be replaced. i't will be 2-3 weeks before I have another seat I'm guessing. In the pic, just above the red there is a more greyish area (from a quick lap) that is there towards the bottom and gone near the top right....that is where the valve is supposed to seat and clearly can't.

On the the next head. The new seats cut WAY different as in way worse than the old seats, same part numbers but very clearly different material...that suck but not the end of the world. Damaged chamber seats cut. then I changed 2 guides...1 cleaned up at about 005 which is fine, the other at 015 so probably replace it. that got me measuring things....hmmmm...why when I drop this valve in the holes in this head is it sitting .010 higher from the deck than when I drop it in the hole in the other head? That is where I ended my night.
Tomorrow I will check the cam to deck distance on both heads. that will tell me if I need to take a bit off 1 head or recut the seats on the other head to make a matching pair. Its not a big difference...but this is supposed to be the no more excuses build....wait a minute....why do the 2 new intakes look different from the old intakes? Oh God damn it they changed the valve design again. Last time I fought with them for months to get 24 that matched...this is a much smaller change.....and 22 more is 800.......fine they valves are close enough, first excuse
New on the right, old, as in 3 years old and different from the 10 year old design on the left. I need a new valve company......
