Iron Head Specialists ???

what are these ? paper weights ? what are they good for ? thxs for the help.

Look like some run of the mill D3's too me.

They are better than having no car........

need to know the cast # from pad at top by the exhaust port, outside. Will be on top left of photo. Probably a D series number. next digit indicates year as in d8 followed by  two more digits. Would mean a 1968 head casting. about 74 cc's. don't sell em to the scrap man, someone needs em for budget street, but not extremely valuable.

Rocker arm pedestal's are wrong for an early head.

X2

only #s i can see are a 36 on one head and a 44 on the other by the spark plug hole. On the top side on top of one of the intake port runner (on both heads)there is a badge like with a # 4L29 .

there is an invoice , looks like they had some exhaust guides done for 235.00 .......

ive got them for zero .... ill just clean them up and wrap them im sure someone might need them

just didnt know if they would be worth taking the grinder too

they can make great power as far as factory iron heads go, the just have big chambers and getting compression needs a decent sized dome.

They are great low buck build stuff

You can cut the decks a whole bunch to get the chamber volumn down

No a D would mean 70's a C8 would be a 1968

Judging by the images uploaded and the date code, they look to be D3VE-A2A's that were cast on November 29, 1984. If they are fully modified and outfitted for max effort use and then used in a max effort application, they should be capable of supporting 1500-2000 hp.

Not N/A

So the letter C,D,E or F doesn't mean 60's , 70's , 80's and 90's ?

Oh no, Dave, I actually did mean NA.

If you are referring to the component's engineering revision then, yes, that is what the letters mean.
