i remember hearing that alabama cylinder head went out of business but couldnt find the details when i searched. according to google they are known as promaxx performance.
they say they were known previously as ACH and still make heads but i was wondering if anyone here knew the details. ie, did a big\gger company buy them out or what. basically if they can still be relied upon to make heads of the quality they used to.
i hear most people have gone with clearwater as an alternative. im just looking to replace my old ones with some stock 93tms.
