Heres the deal.. About one month after the kit was installed by a speed shop I noticed I would run low on oil. The engine was pulled and all gaskets were replaced and the kit was installed. No oil was leaking from the car. This was my weekend car and wasnt driven very often so I thought it was a fluke. Later I got so tired of it I took it to the shop that installed it and they pulled the heads and saw that the valve guides needed to be replaced- with less than 1 k miles. The cost to fix them and labor was 900$. They put my heads back on and told me to call Holley like Rick91GT did. After they ducked my DAILY phone calls,email messages, and phone messages for about 3 MONTHS.I finally got through to someone who could make a call. During the 3 months I talked to several people who all told me that they have many problems with the 190./1.60 heads. The head guy told me that it sucked that I was 1 month out of the one year warranty and there was nothing they could do. He then asked me what I was going to do, I told him if these heads are so cheap- why would I pay 900 to fix them. I told him i`d replace their heads with Track Heat and be done with it. Sorry for the length, but I wanted to give you guys the heads up on their customer service.
Good Luck
