A pal of mine got these in trade and doesn't need them. They're all fresh, but came off a running engine so they'll get cleaned up before being sold. 500 takes everything.
He doesn't know for certain, but he says they've been recently machined and 2.02/1.60 valves were installed, along with new springs and a resurfacing job. We're taking them to TPIS to get cleaned up, and they'll get measured and evaluated while they're apart. I'll have more info then, and they'll be cleaned, bagged, and ready to install.
I looked them over- they were done recently. The story is the previous owner used them in a roundy round car. He couldn't afford it this season (2012), so he parted it out and sold it. He owed this pal of mine some money, so he gave him the heads/intake/rockers in lieu of cash. This pal of mine doesn't need them...so he asked me what to do with them. I told him he couldn't do anything with them til he knew what they were...so, they're headed to the shop for cleanup/measurements and will be ready to bolt on once we get them back.
He's also got a bare 402 BB, if anyone is interested in that.
