Default who makes the alum BBC heads for merc?

Im looking at some used aluminum heads that say "mercury" on them. From a 700SCI Motor. Who makes those ? I am wondering what they are? Obviously they make 700 HP with a blower. Any Clues?

Yup.

Be careful, they (525efi and 700sci) have a different to them exhaust bolt pattern than all other bbc heads.

I lose at least 20 minutes of trouble shooting time each season from not immediately checking the lanyards.
