Guy posted he had some Olds heads and i was wondering what to offer.  Here is his description.  I talked to him and said they had about 3 hrs on them.
"I have a set of Ka heads with VERY few hours on them since rebuild. They have stainless valves and performance springs, comp roller tip rocks, 5/16 guide plates...if you are interested, please make me an offer for however much or little of it you want."
