What SBC 400 heads are these!?
Can anyone identify these heads without the casting numbers? I can’t get home to see the casting numbers for a couple days and I’m trying to order parts so I had my kid send me pics!

The motor is a SBC 400 with TPI fuel injection. Here are the pics.

They each have “20348” stamped on the front of them.

Any info or even a possible date range would be awesome. Thank you!

Ouch I have been there. They are not the worst but more like getting kicked in the nuts with a tennis shoe vs a steel toed boot

882. Best of the worst castings. You can do much better.
Any SBC head will fit onto a 400 block if you drill the steam holes in the head.
