I limped into ABQ with my 6.0L Powerstroke diesel overheating and 179,000 on the odometer (N. TX is home). I'd had the head bolts and new gaskets done at 125,000, but the heads had not been replaced. Daniel recommended the heads be replaced this go round. He did oil pump, oil cooler, and water pump too.  They followed factory head torquing procedure meticulously, which is crucial. It was a costly job, but five months later and no signs of trouble.  Very pleased with thoroughness and candor of these guys. Highly recommend. - John H. (5 star review on Yelp)
