I'm looking for a set of small chamber, oval port big block Chevy heads. I would like to swap out the heads on my 454 which came out of a 1988 C30 Dually. The engine has peanut ports and steel shims at the moment. I'm looking to find a set of 100cc (Roughly) oval ports to throw on there after some bigger valves and porting. I would just throw on the 049's I have sittin in the corner but I don't have the budget to install domes at the moment, so my question is what casting number heads will fit the bill for what I'm looking for? BTW I don't care if they came off of a 366 truck engine or a 454, either way I'll achieve what I'm after.

Thanks Bob! I ended up finding a set of late 60's propane heads for $50. Tiny valves but I'm going to pull the valves out of my peanut ports and cut the new heads for those.
