Seems the real issue is you are stuck with mismatched parts you can't use. I always thought Aruzza was supposed to be a stand up guy. Let me see if I have this right. He sold you valve covers that are taller and then he sold you spark plug tubes for these valve covers that he sold to you. BUT the spark plug tubes are too long to work with the valve covers. And now he will not take the tubes back and refund the money for them. What a low class move.. Reminds me of a Hemi I was going to buy from a guy in FL a few yrs. ago. that he said Aruzza had built with all new parts. The crank was not new, but was a used Funny car piece with cracks and the mains and rods were turned 20 thou each. He would not refund this guys money either.
