Looking for an alternative to my current heads. They are ETP C5R 265's. Flowed at 390/270@.700 My cam is basically a Pro Stock cam 282/304 - 929/925 That said, the more my heads flow, the better off I am. Any ideas. Obviously, this isn't a budget build...LOL Looking for something that flows closer to 500/350
Thanks in advance.

A lot more info is needed to make any kind of educated guess as to what would be an appropriate cylinder head. "The more flow, the better" mentality is a very poor mentality to have when selecting heads. There really is a lot more to it if you are trying to go fast.

This isn't really an advanced topic so it really doesn't belong in the Advanced Tech section. This belongs in an Internals section.

NO: "Which heads are the best?"
YES: "What are the desirable characteristics of intake port design, in terms of velocity, flow, and surface texture?"

LOL, hey I don't make the rules. No need to get butthurt. What belongs in this section is clearly outlined in the guidlines. I guess you missed it, so let me help you out some more.
Your post sounds a lot more like "what heads are best" example, rather than the more technical example.

I have all of the technical data from my motor required to build what I want, I only need someone who can provide the product or service required for my goals. I posted in here because I'm asking for something that might be a bit more pricey (and complicated) than anything discussed in the regular sections of the board. So, am I asking who has the best off theshelf heads? No. I am looking for a professional head porter or designer that can meet my goals. Again, no budget or limit here....

Jeez...Ok. Let me clarify. I am looking for someone who can port (or recommend) a head that will flow in the range specified. Do you really think that there is ANYONE in the "regular" sections who have that kind of information? I guess I would have been better off just picking up the phone and talking to Robin or (Pro Stock) John...

The fastest All Motor LSX stuff seems to be coming out of Texas, so that's where I would start if I were you. Casey Snyder has been doing the heads for the SAM team and there is also Greg Goode, who did Joe and Amber Honeycutt's heads, and they're both out of Houston literally within a few miles of eachother. I'm 100% sure either one of those guys will get you where you want to be.

As I said. I have ETP C5R 265 Heads that are CNC factory ported. I'm looking for a true wizard. Cary is too busy building his business to deal with a one-off like me. That is the primary reason I posted in here. The usual suspects just don't cut it...

All of that said, I believe that the heads I have are an excellent match for my goals. Just need to massage them further. The design of my shortblock/cam/intake/heads are as good as they can be except for the flow of my heads. Trust me, Don Bailey helped design my cam based on all the data and it's as good as it can get. Except for head flow, If I had 100 more CFM, I'd have 200+ more HP on the top end and THAT is what I'm looking for.
My hopes are high....Thanks for the input! I'm looking for 1000HP out of my 457...Oh, did I mention that I'm going to spray it? 500 to start...

Not sure that will do what I want. I have a few calls and emails into Cary. I have a perfectly good Beck intake that flows like there's no tomorrow. I just need the heads massaged. I put money on it that they will do the job.

I would think the Edelbrock castings would be a great start, but since the guys at SAM have made 1000 hp with C5R castings, and since you already have them, get in touch with Casey like someone else said. Since those guys at SAM now have a CNC machine, I would bet getting stuff done will be easier.
