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

here it is:

You most likely got a "standard" flow sheet, probably the same one that goes out with all their Stage II E heads. Kinda sucks, especially since they are hand ported, they could flow signifigantly better/worse than that. Are they 5.3s or 5.7s? The numbers seem average IMO, but MTIs heads have always performed well, and have never had extremely high flow numbers that I have seen.

MTI is supposed to have records of all their heads by the purchasers name. Call them and try to get the REAL sheet faxed.

Yeah, good luck with that. I dealt with them last year and had the same problem. Got the heads, no flow sheet, that is "sent with every set of heads". Called and requested MY flow sheet, got a GENERIC flow sheet. whatever..NOT impressed with their customer service, for that reason, and too many others too list.

Silvervette73

on the flow sheet it says LS1, so i take it its the 5.7
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.

Silvervette73

customer service has been ok. not the greatest.
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.

nasty99WS6

Well, I am an a4, sooooo, they DO dyno lower. BUT, yeah, I was difinetly hoping for more. If you are a m6, I would excpect you to be near or over 400 rwhp with any cam my size or larger. 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.

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 ***.

Silvervette73

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

Silvervette73

nice.

nasty99WS6

What cam are you running? Running the converter locked on the dyno will show more rwhp. Mine was unlocked. With a bigger cam and locked converter on the dyno you will be around 400 rwhp. let me know.

Silvervette73

the cam is mti stealth II .224/.220 .581 116lsa it will be 2-3 weeks before everything is on and probably another month before dyno tuning pending no hurricanes come visit us here in florida

nasty99WS6

That cam is similar in size to mine,If 400rwhp is what you are looking for, Why dont you step up to a f13 or f14. I have heard that with a good tune, they idle very well, and have proven results.
