This guy I can feel comfortable with recommending and I also put my money where my mouth is by buying his stuff and sending him stuff to do. Honest and will do what he says.

His brand new CNC 18 0r 15 deg heads are very good right when you get them. He buys semi-bare bastings unported from EDlebrock and then installs his own port design into them.
AS far as out of the box bigger heads I too like the AFR 227 or the Canfield 220. AFR can use stud rockers though.
Frank at Advanced who is in this thread also has a good reputation so you can pretty much be asured he will also do you right.
Do not go by anything BRodix is advertising as anything near what thier heads actually do. They lie.
I just had two examples of ther trick CNC Heads in my shop and both were very miserable compared to advertised. The best most expensive BB Chevy head they sell is advertised at 571 cfm. You will not find one cylinder head guy in the country who has ever gotten even close to what they are claiming on their benches. Brodix says the head is flowed at 25 inches and that is conveted to 28 inches on that head. Bull!. Out of three different flow benches no one could get it to pull as much as 530 cfm. The other fine example is a new CNC 15 degree head That Weld TECH was supposed to put an awsum port job on before the sale. Advertised at 370 cfm and in reality barely a 350 cfm. I sent those to Curtis last week to get him to wake them up. Brand new heads should do reasonably near what they advertise. Bridix does not come close. Not only that the 15 degree head exhaust. stopped pulling at .600 lift and just held it up to 1 inch. Neither of these two heads were cheap.
Brodix makes a good casting but lies big time about the flow.
