340x vs. Edelbrock aluminum heads.

Hey DOn! Long time no see. Glad to see your still looking around at stuff and finding out whats what with things.
If you get a chance, paste and copy/lik to the write up on the heads if you will.
Considering the price tag of $439.00 as compared to a SET of the Eddy's
$439 per head right? $878 per pair then, correct? $370+ in savings.
Cost of remain parts to complete the deal?
