Help I.D ing these aluminum heads please?

They are Mopar Performance heads sold thru Mopar Dealers only 10 years
ago or even a little more ago.
Cast by Edelbrock and identical except for straight plugs the best
I could ever tell by visual inspection.

They are discontinued and I believe probably accepted for
some NHRA Superstock Classes.
I will research it when I get a chance.
If they are accepted for NHRA = They are worth a small
fortune.

I have paid many thousands for the discontinued NHRA accepted
Small block Aluminum heads that were made for Mopar and one
particular number different from all regular Edelbrock small block
Mopar heads.

By the time they are ready for Mopar stock to make specs which are
all totally everything machined total off from idiots at Edelbrock
(Wrong Valve seat and guide size/Runners way too crazy big)
you will have $13,000 to 15,000. in a pair for stock eliminator.

None of the above can you do yourself.

When you are done you gain 10 to 15 HP over the Iron heads and
have a very fussy car for temperature for consistence.
