According to Edelbrock's webpage, I don't even see the heads listed?
I went to look up the flow numbers and couldn't find em.
Edelbrock BBC aluminum cylinder heads (http://www.edelbrock.com/automotive_new/mc/heads/chevrolet_bb_performer.shtml)
They show a #60469 bare----- #60479 setup ready to run
and #60489 bare----- #60499 setup ready to run.
Hmmmn interesting. Went back and did a search and found em here.
Carshop inc. (http://edelbrock.carshopinc.com/product_info.php/products_id/20445/61459)
Still can't find em on Edelbrock's site though.

I added flow numbers from Edelbrock. Is this what you get with these heads or with chevy 049 heads?
