ET Performance flow numbers and impressions
How do these heads compare with the AFR 225 head? I am doing a LS-2 402 buildup with a fast 90/90 setup. I already ordered my AFR 225 heads 2 months ago from AFR and they were supposed to take 4-5 weeks and I'm starting to get sick of waiting. Nobody that I called has the AFR 225 heads in stock either. I may just get a refund and look into another type of head but not sure on my options.
Thanks

mrbowtie, from the flow numbers they are outdoing the afrs.
Cary/ETP I'll agree with JRP, keep that handy, and a good writeup of volumes/options/etc/etc w/ retail pricing would be greatly benificial.
Could even be setup in a table (or on your website, as a table) so it coudl easily be transfered here..

[QUOTE=Brandon]mrbowtie, from the flow numbers they are outdoing the afrs.
The flow numbers on the intake is very good but it seems the flow on the exhaust is less than the AFR head. Any idea if the flow on the intake side is more important. I see that the biggest valves that the ET 240 heads come with on the exhaust is 1.57.
Thanks

[QUOTE=Mrbowtie26] Part of the reason is AFR is using a pipe, ET is not. Add the pipe and watch the flow increase considerably (+20-30).

Can you elaborate more on this?

Our 265 does use an offset rocker (avalible from Jesel) Racer net at 1430.00 for the mohawk series. We will offer them cheaper with the cylinder head purchase. All of these will fit a stock style manifold as well. Our LS7 is very similar to the GM LS7. We offer them set up fot the Jesel C5R style rocker right now until the GM rockers are readily avalible. the price on 225 fully assembled with SEVERE DUTY valves and hyd. roller springs is 2475.00 C5R and LS7's will be under 3500.00 complete

What is the difference between your 11 deg head and the new gm ls7 head coming out other than the ls7 intake ports are totally different and they need the ls7 intake to work. What do you mean when you say our ls7? Do you call your 11 deg ls1 heads ls7? Are they your own casting design? Thanks for clearing this all up.

hey cary i was looking into your 215s for my 347 which already has the f13 in it and i saw you have 2 versions....the 11 deg and the 15deg
i saw the flow numbers and noticed that at.400 to .600 lift the number are the same but the new angle helps in low lift and very high lift areas
so with a cam that is below 600 lift these heads would not be a big improvement over the 15 deg heads
what do you think?

Our 11 degree actually flows a bit better than the flow model numbers posted on the website, we have made some valve and seat angle/combustion chamber changes that increased the 215's /11 degree.
all and all the 11 degree has other features that would make them a choice over the 15 degree. other than airflow.
Is there a price breakdown somewhere. I checked on g-force's site and saw nothing as well as the etp site.
I am basically just looking for a set of the 255's for my next project.
