How much do CFE heads cost?
I think your mistaken, Eds talking about CFM (Flow)

You can get some profilers assembled ready to go for about a grand and they can most likely handle the reverse coolant conversion too, so I'd say around 1500 you'd have a killer head.

In fact there is enough meat in those heads to raise the entire runner making them a raised runner

I'm not. Reread what he wrote. And why are you or no one else running them on lt1's? That would be cheaper than my Ai heads. Not saying ur wrong. More than one way to skin a cat.

I have talked to them twice about a set for mine, but it was a couple of years ago. I don't remember the price, but they were higher than most others. More than most would want to spend on a street car.

The terms used in our shop were "velocity maps/air speed, choke points, CFM" as you stated. A lot of work was put into straightening the airflow.

I worked at NRP with Gil Nevarez. I used to do all the electrical work and Computer tuning on the cars. He now works at Shelby here in Las Vegas.

I also worked at Combination Motorsports. I did the same there. Bryan Herter was the one that showed me and instructed me on LT1/LS1 tuning back in late 2004. I learned a lot from him and did very well from it.

I have since moved on and now work for a contractor at Nellis AFB. Racing takes way too much time for the money made.
Gil knows his stuff. I had a Nevarez Racing/Cmotorsports ground cam in 05 around when they were merging and their sites linked to each other. Was very happy with it, was just what I wanted. Motor still runs strong, probably throwing it in an old rx7 tin can for some fun with it once the new stroker is set up in the Z.

There are a lot of great SBC heads available that are just a conversion away from LT1 use, but most cars are still street cars that want a simple, proven, bolt-on solution like ported stockers or out of the box aftermarket heads.

Time and money add up fast .

I don't know what that is. I was pretty sure it wasn't NHRA since I hadn't heard of them. Don't guess I've seen that series run.

Pacific Street Car Association is a pretty well known series from the West coast. I live in Chicago and I've heard of hit, but never been part of it. From what I've seen the cars are very fast and good at what they do. Personally it seems like the street racers going to the track, and going overboard. Not that it's a bad thing. IIRC It was originally dominated by back halfed cars and and "Pro Street" cars. From what I've seen it's jumped to full tube chassis cars and Top classes are running very nice single digit times. But definitely a West coast series.

I'm getting ready to build almost the exact same setup from LE, except with 13.5+ compression and E85. Let me know how yours turn out.

It's going in an autox/RR/weekend car, I'm hoping for ~475rwhp out of it, hoping to have some nice throttle response with the high compression

My setup will be here monday. I'm really excited to finally see what it will do. Forged 396 with 11.5-12:1 "have to do the final calculations with my head gasket" TFS 21 degrees with Lloyd doing his magic. 237/245 603.619 on a 110 and then a 200 hit to top it all off

I will be running a Nitrous Outlet Money Maker kit on my car. I was contemplating a standard plate or possibly a direct port but since ive restored it back to a stock look, I decided on the money maker kit tokeep the sleeper look going.
