Trench is in Nova Scotia Canada which is why maybe he was looking at canadian sites. I also think PW is an Import brand and company located in BC and supplies a speed shop up here called Mopac. Maybe PW is owned by Mopac, Not 100% sure on that one though...
I think the heads from JB’s also have free shipping Trench. I like the smaller closed chamber style of these that way you can rake it out of the pistons if you have to and will or can have a lighter rotating assembly...
Interesting fact too: the E-street heads are the identical casting number as the RPM performer heads. I asked edelbrock and they said they use different metallurgy in the valves and seats which is where the extra money goes for RPM heads. I think it’s marketing, two different crowds, same part. Two in one box and the other sold separately for more. There will always be people who associate more money with better which doesn’t always hold true
