Looks like you have a 455 block with 455 heads! :D
I couldn't resist....

If I am remembering correctly.
The F blocks are late 60's to early 71 blocks. Rumored to have higher nickel content. Supposedly the higher nickel content makes for a strongr block.
Ga Head... Later early 70's emissions head...
I am going off of memory. Check realoldspower or another site like that...
