I figured out why Patriot closed up and changed its name. I ordered a set of their cast iron heads, bolted them onto the motor, and noticed something was off. Well 2 sets of intake gaskets and 3 intakes later I measured the heads and all of the holes and ports on one head were 60 thousandths off from the other one. Ok, somebody stuck it in the CNC wrong, no big deal it happens. I called the company and spoke with the owner. He tells me he'll go measure one and call me back in 15 minutes. An hour goes by and I get upset. I called him back and asked what the measurements were. "Oh I haven't been out there yet". Really dude? Then he tells me its because of the head gaskets I used. Really??? My heads are off because I used the gaskets YOU specified in the instructions? At this point I got upset and told him I'm now out the cost of head gaskets, intake gaskets, and primer, base coat, and clear coat since I had already painted the heads. I told him no matter what gaskets I used it doesn't excuse the fact that two identical heads measure differently! We worked out a deal where I could upgrade to their aluminum heads and he would include the gaskets and shipping. Great! Except he never sent me an invoice or shipping details and now won't return my calls. This is a week later by the way. Plenty of time to write up one invoice. I ended up calling Jegs to just return them and decided to go with a better brand. Long story short... if anybody is considering buying heads from them, measure everything as soon as you open the box and don't expect any kind of customer service from these people.
