Trick Flow heads

Cutting to fit for that pan has been a known issue for about 15+ years.

The fact it leaks OOTB from bad manufacturing processes is the bigger issue!
Summit gave me a discount and milodon said I could send it in and they would send me a new one but you know how that goes. They get it inspected and tell me it wasn't their fault and I'm out my oil pan for a month-and-a-half and then I have to glue on that pile of crap again. It's working now and doesn't leak...
