I finally got the heads off my engine. First tear down of a V8. Better late than never.
1. Engine painted blue not stock.
2. Pretty sure a rebuild. it has overheat indicators on the heads. Pioneer 580 plugs on the ends of the heads.
3. Pistons are not original. Stamped 345np .040 dual valve reliefs pn#02-233-04b.
Any ideas on the pistons and heads being an upgrade or just a replacement?
Thanks for all the help.
