Thanks for all the advice! I'll just wait to gather the all the parts then put them on. Where is the best place to get these heads? Junkyard? I was going to get them from a local O'reilly's for about 250 a piece with a $65 core charge, everything thing is included but I feel like it's a bit pricey. I have checked the local junkyards and haven't found any small block dodges to scavenge the parts from.
