Ported Champion iron heads with T&D 1.65 Roller rockers with push rods and arp head studs. I bought them about 6 months ago used. The person I got them from said they had a few hundred miles on them and I believed him buy the way they looked. I never ended up using them and now going a different direction. The heads are set up for a roller cam. The cam he said he used was a comp 212. I don't have the cam or lifters. I do not want to separate. $1200+shipping
