We just have to see how much of that we'll need/want.....
Btw... I'm currently assembling the lowport SR20 head from a few weeks ago. It came back from the machine shop nice and clean. I cleaned, and de-carboned the valves... and began lapping them into their seats.
As far as if this client should have gotten a 3 angle, I told him his options, and because he doesn't want to drop a lot of green... I lapped the valves into their seats. As you can see, the far left view shows the "rough" valve and seat, the middle shows most of the two surfaces refinished, and the far right view shows a lapped exhaust seat.
More to come.....
