Just need to tip the valves, and then it's time for assembly, my favourite part!

That's a shiny head!

When we measured the stem length on the '52, only 4 of them were out of spec (not enough clearance). Most everything was at the minimum end of the spec range. They all ended up between 0.030" and 0.045" of clearance. With the seat grinding and valve facing, my guess is they will sit lower in the seat, so depending on how tight they were before you may need to face the stems on a few of them.

Getting close!

I just had the head resurfaced. The shop also cleaned up above the intake valve for each cylinder. They're trying to make my 327 into a high performance engine!

I don't have a valve grinder, so my engine builder will tip the stems for me. (He also did the faces for me.) He's got a slick setup so once he knows how much to grind off, which I gave him, it doesn't take long at all. He's going to even them all up. They'll all be .050" + or -
