Interesting, the exhaust ports are smaller than stock?
They`re calling them oval but look like stock rectangle ports with corners more rounded.

I'm sure you have all kinds of free time to call... and $2000 burning a hole in your pocket. I don't have either at the moment, but thanks for the snark.
If you were applying YOUR "common sense" you would have realized that my question was really a comment on the uselessness of Summit's catalog entry. It's equally obvious to me that I could have called the manufacturer. Jeez.
Trick flow has the specs on their website.
The solid roller springs are really serious. 240 on the seat and 500 lb/inch rate so 600 lbs over the nose with a .700 lift cam.
The solid roller setup comes out of the box with 2.00 installed height which is great. It takes a bunch of work to get that much installed height on some of the other heads on the market. A 2.00 installed height can handle .850 lift with a Manley 221424 spring. Not sure what the rocker arm geometry looks like at that lift so it might not be practical, but on paper it works.
People need to remember that these TF heads will have a 78cc chamber so the CR will be higher than with the Edelbrock RPM heads.

I'm rounding up the parts for a pump gas 470 that will use the TF heads. I'm shooting for 650 hp with a 850 DP carb. It might make even more than that depending on how big of cam I slide in there.
any news on the release date of these?

I have a question on thier Facebook page about the relese date of July ... have not heard anything yet .... I had my solid roller cam ground to the 78cc combustion chamber size ... should be fun ...

Now I'm thinking of B1bs or ez
I think the TF heads would be better than the EZ heads if you're going to run them as std ports. If you want max wedge size ports then the EZ heads would be the way to go. I don't know much about the B1-BS heads. Haven't seen any of those for a really long time.

Are those Max-Wedge port size?my victor knock-offs flow 352 @ .600----------------------------

Too bad the Edelbrock engineers didn't put a longer valve in the Victor head. The Trick Flow heads come out of the box with 2.00 installed height. I think the last set of Victor heads I worked on only had 1.800 installed height?

On Trickflow's Facebook page on the left side column they answered the guy above me and said it would be like Sept or Oct .... so I'm going to look at EZ's .... EDIT: just ordered EZ's from Muscle Motors with CNC work
Yeah...thanks summit for getting my hopes up by putting in your catalog.....

Yeah, but they've been doing it for years. I almost wonder if they do it to gauge the interest level...
did they tell you what year?

I contacted Summit and Trick Flow this morning. They say the heads won't be available until October.
