YIKES! those are some incredible flow numbers

can't wait to see how they perform.

 

We are dealers for E.T. Heads, if you guys have questions, need info or want to place orders we can help you out.

 

Prices???

 

on which set

 

How about all of them....

 

Yeah... Also what are the chamber size options?

 

you can go anywhere from about 48-72 cc on the chamber. you can realistically go smaller than 48 but it cost more and the bolt holes will have to be adjusted unless you are using a sheet metal intake or somekind of custom intake manifold.

you can also get enconel valves price to be determined.

on the 265 heads you must by the custom Jessel rocker arms from et performance as the stock or stock replacements will not work. price on those will be around $1600. on the other heads you will need to buy the rocker stand or the jessel rockers.

These are retail price. as of now i will not advertise anything other than retail but for best price pm or email or call.

 

Cool deal, thank you sir.

 

What is the lead time on getting these heads? Have anything ready to go?

 

not yet but we will very soon.

 

Hate to bring this up from the bottom, but could somebody post a flow sheet for the 255 CC heads. It looks like they were skipped over. Thanks...

 

Have any of these heads shipped yet? Are they on anyone's engine yet? Has anyone other than ET had them on a flow bench to verify these #'s are no BS? If I want a set of the big dogs, how long before they are in my hands?

Very interested...

 

i know a few places have them. if you look at some of the pictures from wheel to wheels site you will see the heads monted on top of an LSx.

 

Thanks!

 

Scott,
Can you or Craig answer my other questions as well please?

I'd love to see these heads on Tony's "list".

 

Yes, They have been flowed at other shops. We've had equal comparisons, most of which were higher than our numbers slightly. If there are any doubts on your end, I would be glad to send a head for flow testing, as long as it were secured. I would not have a problem sending one to Tony as I am sure someone else would anyhow. We are currently shipping certain part numbers right now, including the LS7 version of our casting.

I've been trying to post pics, says file is too big. Help!!

I would email pics to someone if they could get them posted up here.
thanks

 

Flowed on a 4.100 bore today
ETP 265 2.100 intake valve 28"

.100 74
.200 160
.300 233
.400 280
.500 326
.550 343
.600 358
.650 368
.700 374
.750 380

This is obviously a large runner, not intended for a 347 inch motor, but it fits into the solid roller race engines or a mild to wild 402/427

 

When will the 255's be ready and flow # for them

 

We are machining 225's in the first part of next week. If you want to order a set I would do it real soon so we can machine those in this batch.

The 255's are not finished as of just yet. We are working on another C5R port and also a Viper head back in the R&D department.
