My experience with Harold left a bad taste in my mouth. Felt like a bait and switch. I emailed asking for price range to rebuild some heads for me. I was estimated $200-$400. Told me $400 was if they were pretty messed up. Called me this morning to tell me that only one of my heads needs work and it was going to be almost $700. That’s more than what a brand new pair of Vortec heads cost at summit Racing . Now, to get my heads back, I have to pay $75 because they scammed me just to get me to bring my heads in. Lesson learned. I will not be doing business or recommending Harold’s machine shop!
