Machinist will not build engine unless roller cam is used!

My friend Mark is having the 327 for his 67 Camaro completely rebuilt by a local reputable performance-oriented machine shop. We took the engine there on Tuesday. The shop is beautiful. I was very impressed. When the shop owner was going over the options with Mark, he added that if he did do a complete rebuild, Mark would have to go with a hydraulic roller cam. He said he was tired of new flat tappet cams failing, so he went to the roller cam policy. He told us that his contact at Comp Cams told him that all the lifters are made in China now, and that Comp did not have the manpower to test each one. The Comp Cams guy admitted that their lifters were flawed.
Just thought you guys would like to know about this.
