Good morning, I have a set of Oldsmobile #10 heads that have been hot-tanked and checked for cracks in bare metal. These come with a box of brand new valves, springs, retainers, keepers, from Ross Racing Engines, everything to give em a fresh rebuild. See pics. I would like to get $500.00 plus shipping for everything. I also have lots of 303/324 speed parts, water logs, starter Crossovers, too much to mention, this stuff will be for sale also.
