Some of you may remember that I bought a set of Roush branded RHS heads about 5 or six months ago. I've been real busy lately but I got a chance to work on them a little this week. All I was doing was polishing the chambers and knocking the casting flash out of the runners and bowls.
I found small hairline cracks in about 4 or 5 of the bowl areas. The cracks are all on the intake bowls and run down the valve guide boss. Some are shorter, maybe 1/2" and the longest is maybe 1 1/2-2". I showed some pictures to my machinist today. He said we could pressure check the heads and see, but he pointed out that cracks just tend to run. He confirmed what I thought and said that the guides were pressed into a hole that was probably not sized properly.
He recommended that I give Roush and/or RHS the opportunity to fix the problem. I told him that I really doubted they would own it, especially since I have had them so long and the fact that I was polishing on them. I called around today to Roush and could never talk to anyone who knew anything. I didn't get a warm and fuzzy from the last guy I spoke to who was going to tell his boss about it when he returned from holiday vacation.
Anyways, have any of you ever seen anything like this before? This is a BRAND NEW set of heads. I can't seem to find anything about it online. It makes me sick to my stomach. My budget heads are going to turn into a new set of AFR's before this is over if they don't own up to this.
