Has anyone heard of these they are suppose to be from Mercury Marine and flow real well or is the #462624 an I just read the head wrong? Did the 462624 come on marine engines?

My chart shows that head coming off '75-'86 350 and 400 engines. 1.94/1.50 valves and 76cc. It's a light=casted head released in the late '70s and is prone to cracking around the exhaust seats when exposed to extreme heat. Would be rated as an intermediate to high performance head depending on valve size.

Sorry about that!! I can't tell the difference in an 8 or 6. The info that I posted is for the 624. I can't find anything for the 462824.
