1967 original 383, factory 10:1 compression rated 325 hp.
Had 2 sunken burnt valves, you know the non hardened seat thing.
As purchased pictured below:

Tore the top end off, sent the heads in for hardened exhaust seats. I bought all new valves and springs for it.
Had a bad experience with the machine shop taking over 6 months to do the simple valve job. Went down there face to face and said I am taking my heads out of here.
The guy had put some work into them and wanted to finish them, he said will be done in two days. Said OK, picked them up in 2 days.
So after this long wait and delaying the project, I have done all of my heads in house from here on out on all of my builds since then.
So back to the 383, fresh heads, put on an Aluminum Passenger side exit water pump for the A Bodies, new timing chain, new points distributor.
That sounds really nice. It's amazing how you can take an original short block and work the heads and get it running like that. That just proves the old saying "it's all in the heads" and it's true.
