Do these stamps look legit?

Thanks again Stingr69. What date range should I be looking for on cylinder heads?

[Stingr69]

Anything before February 26th '69 would work. 

[HustleRussell]

Okay thanks again. Here's the intake.

Hard to tell but date looks to be B 6 9. 

[Kelley W King]

I think B 5 9 with my glasses on

[cook_dw]

You are correct. I missed it.
