I just got my heads back from the machine shop, had a 3-angle valve job done, hardened seats put in the exhaust, new intake valves and seals.

When I got them home on the workbench, I saw a bunch of silica sand stuck to the head in multiple places (first picture), and a pile of sand in the bottom of the bags the heads were in (machine shop bags - heavy plastic clear ones). I was disapointed, and I thought I should take the heads apart and clean out the sand.

When I got the valves out I was shocked at the rough surface of the valve seat. Please see pic #2 and let me know if this is acceptable at all to run, or if I should take the heads somewhere else for another valve job.

Heads are 6X (95cc chambers), going on a 462 with a stump puller cam and rpm intake.

thanks,
Jeremy
