Yes those are the right pistons. If you are going to order them, order +.005 and have the pistons fitted to the cylinders.
just cleaning up the ports, doing a good 5 angle valve job, and equalizing combustion chamber volumes.
In days gone by (automotive world) i have done a few valve jobs, all dealer work.
Typically they were 1 angle. If we were doing the work for a "special" reason then I would do a 3 angle, and 5 angle wasn't in the picture back then.
But seeing the way heads, pistons and valves looked after thousands of miles, I am curious as to the long term benefits of going through the trouble of a 5 angle or fitting the pistons exactly to the cylinders.
Does it really continue to be an effective 10-20-30,000 mile down the road?
