MTI Stage II E heads just came in, here are the flow #'s
Had them Fax the flow sheets to me since they didnt come with the heads. The only weird thing is that they had told me they were finishing the heads last week, and the test time on the flow sheet is 5-25-2005

The numbers seem average IMO, but MTIs heads have always performed well, and have never had extremely high flow numbers that I have seen.

now i am using stealthII cam, and with specs .224-.220 .581 116lsa i dont think that even if the heads flow alot better, the cam would not bring out much more hp, am i right??
hope the heads flow good.

are you happy with the heads? i thought their heads and cam would give close to 400rwhp, but i see in your sig you're making 363???? did you expect that result or were you shocked? i am making 349hp/355 tq before the heads/cam LS6 intake and puleys. thanks.

I have a set of Stage 2's by MTI that made 438rwhp with a G1 cam and a nitrous tune. Made 406rwhp with a LS6 cam and a nitrous tune.
My car has MTI Stage 3 LS6s and they are still kicking ***.

My latest issue with them is this: I bought this package last year, did the swap and never sent the heads back for the refund. MY bad. I cleaned out my garage and came across the heads. I email them saying that i KNOW it was way past their core refund time, but do they want them. They say yes we do, please send them and we will refund you. I have a tracking confirmation that they got the heads on 5-17-05. I wait until 6-7-05 before I inquire if they got the heads or not. On 6-10-05 they say " we got them, will send refund". 2 weeks later, no refund. sorry, again just venting. anyway, good luck and I cant say if I am pleased with them because I havent had any other aftermarket heads to compare them with. More powerful than before? yes, definetly. Bad taste in my mouth from cs, Oh yeah.
mine is an auto also, and i sure hope i get more rwhp than that. who did the tuning for you? i would check everything out, those numbers are low for your mods.
now i have to wait for pulleys. they have been telling me 2 weeks for about 2 months now. seems there is a shortage. damn it, i want my heads and cam on the car already
