As for out flowing an LT1 head, thats debatable as the vortech heads are based on the LT1 iron head design and flow about the same.

was for the statement that you could bolt the vortec heads to an LT1 and all you've got to do is mod for the intake. Before making statements like that you should research the subject. You bolt vortec heads on an LT1, start it up and in no time you'll burn up the engine because no coolant is flowing through it.The vortec intake, exhaust and combustion chamber designs are based on the iron LT1 head (which flows better than the aluminum head BTW). Thats why I made the statement about the vortec head being based on the iron LT1 head, not because they are fully compatible with each other. The same thing as stated above goes for bolting LT1 heads to a standard SBC. You do that, start it up and pretty soon it'll overheat big time because no coolant is flowing.

DAAAAAMN!!!!!!
I just read through this thread and could not believe this.
I have been working with cyl heads for many years and have done my share of porting. Dude, I would go back and kick this guys ***. But the truth is, there are so many of these guys out there, it's unreal. My profession requires me to move every couple of years and everytime I move I have to find new, reputible shops. I run into alot of this stuff. If you talk to enough ppl, you will get pros and cons for EVERY shop out there.
Zcarguy, you da man. I'm glad someone pointed out about the iron head being the preceding design for the vortech.
My suggestion would be mail order. You have no one close so your stuck with mail order. Plus, places like Patriot, LE, etc. You're getting high quality products.
Go back and tell this "machinist" all the car lover world says he's a f^(kin MORON.

There are a lot of people with careers in the automotive feild that don't know jack. It is just a job to them and too few people take pride in their work these days, combine that with the lack of true knowledge among enthusiasts and the weeds never get sorted out. Most of that guys customers probably do a cam at the same time as the heads, he could spend lots of time and not improve flow then when they people get a power boost from bolting in the cam and on the heads they think they did OK, when all of the power may have come from the cam, they don't know.
When I go to the race track be it dirt oval or drags I am amazed at how little most of the people know, even guys that assemble their own motors. I know a guy that used to run a single digit drag car then dirt track cars for a combined time of over 20 years and assembled a lot of his own engines and he tried to tell me that on the 383 in his sons dirt track car they increased the stroke by using longer rods! I try not to talk cars with him anymore, our wives are good friends though so it is hard to avoid.

LOL Maybe HIS heads never made 400 RWHP on a stock bottom end LT1. I like how stalls dont help, I mean they only throw you into your torque curve/peak. Shoulda asked him how much he'd charge for a muffler bearing change and some blinker fluid.
