I am looking at a set of edlebrock performer rpm heads with 1.6 roller rockers and a comp cam XR265 hydraulic roller cam .506" - .506" lift, 216^-224^ duration at .050". The guy wants $1,100 for all this. not sure if its a steal but it does sound like a deal. 3,000 miles on them he said. Im not sure if i will actually use this cam for my stroker motor. i have to do some more research
