Blocks at the shop to get checked, cleaned, and bored.
Parts are starting to show up. Shop didn't say anything about needing the pistons yet

. But they probably haven't started on it either.
I have the springs, and the locks/retainers are supposed to be here tomorrow.
So hopefully I'll get started on lapping the valves and changing springs tomorrow evening.
I have a leverage style spring compressor. So I'm going to bolt a head to a steel table to remove all the springs. Then unbolt it, make sure the valves stay in the right place, lap em all, and bolt it back down to install the new springs/locks.
With any luck I'll have the heads ready to go by Saturday.
Block may be a while though.
