I can't believe how wrong most people are about their cylinder head beliefs. Having the tools you have and the experience from working on many different designs just makes your explainations so easy to understand. Thanks for your time, I appreciate the knowledge you share. Cheers from Canada.
The W2 design dates back to about 1974 with the actual release being 1976 for the econo head. Considering roughly 35 years separating the two heads I think the W2 shines bright. A matching valve as the Trickflow has would show just how good Mr Mullen was when he designed the W2. I would put the W2 up against anything made out of iron as long as it has the same cubic inch, cam specs, and compression, and that includes the Cleveland if it had it's original exhaust flange to bolt a header onto.
Good comments. I’ve heard or read several times that the W2 or something quite similar, was also meant to into production but by the later 70’s times had changed. Don’t know how true that is though. Maybe I missed it in the video but the TrickFlow doesn’t require offset rockers like the W2 though, does it?
I am looking forward to seeing what you can do with fresh heads and 2.08 intakes. These tests make the 302’s even more impressive for a .450-.5 lift cammed vehicle
You know what Chuck, I didn't notice this before, but those heads only have one set of threads drill to either side. There is an alternate bolt flange pattern that is 45° to the centerline of the original port. It's been years since I ported a set of TFS Hp's, and until you noted your disappointment with the exhaust it hadn't clicked. The set of bolt holes you have get filled in max effort situations. Trickflow cnc's a large oval port maybe a hundred thou from those bolt holes and the angular bolt pattern is used. For a 2" primary I've threaded in a solid piece of aluminum with JB Weld and ground my port in accordingly. Same with the AFR 205's and 225's. Widening does wonders as well for exhaust flow. I think that's why you're underwhelmed and skeptical to all the hype talk about how great they are.
The first W2 heads were introduced in the 1970s and Mopar still offers them for 48° blocks(r3, Ritter) Mancini sells bare heads for $200 ea, but that's just the beginning as a user will need to round up all the special bits to make them work. I don't recall when the rest of the W heads were released but the Ritter-Weber E/A car had prototype W9s in 1992 or 1993.
Hi Charlie. It's interesting that the W2's have a more efficient port shape but you got so much more flow from the Trick Flows. I know you said that the Trick flows had more work done to them though. Interesting to compare different port designs. Do you think that with more work the W2's will be able to equal the lower lift flow of the Trick flow heads? Andrew
Charles please get just a little more animated/excited on camera you do great work but its extremely hard to follow videos they can be boring when you are so monotone

Thanks John, I try

I like the design too!
If you believe Herb Mc Candless the W2 date back to 68 69 but the HEMI ruled they shelved the W2

I am sure you are the only one who noticed. Thanks
Now I see they aren't a Mopar head. Carry on.
Great education on historical heads. Thank you
Glad you like it.
Your experience shows in your work! The finish that you get with a grinder in your hands looks more like a machine did it!
It is my only talent!
Thanks
Comparisons are interesting tnx Charles. Ow, if you ask me, the trikflow heads look bad ass.
Thanks

Good info, thanks
I would love to see the numbers of a fully ported, big valve, closed chamber 48* W2, with current seat angle technology.
So would I, stay tuned.
Weren't the W2s from the 70s. They Moved on to W5s and the W7/W8s later. Those trick Flows from same era?
I have no idea.

You still can get W2 for a 59 tappet engine I’ve not seen eco heads for a while
Released 1975

The trick flows have a bit bigger valve too. I may not have mentioned that. I think the W2 would love bigger valves.
The oldest W2 to modern iron technology
That's a Ford head, apparently you know that, so why the comparison
Different design philosophy. Always interesting.
Shows since they flow similar they will be able to support similar power too.
Charles please get just a little more animated/excited on camera you do great work but its extremely hard to follow videos they can be boring when you are so monotone
Yep, more dead than alive.
Don't remember trickflow iron heads for a mopar
They are for Ford. Different design.
