Mopar 340 Heads

Hello All
I bought them last night. Offered him 300.00 and he took it drove two hours in the rain to get them. I wanted Aluminum Heads for a 408 I'm building for my lifted Grand Cherokee and don't want edelbrock for personal reasons. I hope I can get these to work if not they'll be for sale. I couldn't pass them up. I'm not looking for a 8 second race engine just a healthy stroker. What do you guys think?
