How many were/are made? I used to have a link to the info on them but it is long gone from my computer. Wasn't there one on some weird auction site (not ebay) a few years ago?
Yeah, they did. Big writeup on their stuff in one of the "Hey Charger" mags in the early '90s. When I rang and asked them about the particulars, they explained to me that they didn't make a head for the slant or hemi six, but they reworked factory heads w/bigger valves and porting, to order.
