ProComp/Speedmaster aluminum heads

I remember it too. Could play it till the batteries died lol. Coleco??
Jealous with the heads JD!
Finally got a chance to open the box and inspect the heads today. While I don't pretend to be a cylinder head expert, they seem to be really well made. I will get advice from a cylinder head shop locally as far as setting them up. Probably going on a 408 build that I'm collecting parts for.

I remember when I was a kid that handheld football game was a real challenge for some reason. Now I tried it as an adult and it was so boring I couldn't believe it...
