Some will say those are really good ProComp heads, they are cut up in pieces!!

How much cost does CNC porting add to the cost?

Out of the box flow #'s would be good to compare. Also if there is any piece to piece variations.

Out of the box their flow numbers are terrible; the valve job is so crude that no matter how good the port, it has no airflow. It can be made to be decent. NOT a race head by any means.
It's a good casting to start with and go from there but, "as is" it's just a chunk of metal like a stock iron head, (except it's aluminum), which NEEDS major improvement.

It's lighter and looks nice though...!

IMO they have their place, but overall I'd rather spend my hard earned money on something American and something of higher quality, better design and something that has better potential for the money spent.

Please verify the source and method of flow testing on those Bruno......

It seems that once you pay for the porting (CNC or hand) you could have bought better out of the box heads and have more room to grow.

I suppose you can make any thing work given enough time and money but sometimes it comes down to spending a dollar to save a dime.

Clown Shoes.....LOL

Those flow numbers MAY be correct for a 300 cc port with a good valve job however, definately NOT "out of the box".
First of all, the intake runner without modification is about 270 cc's and max flow with a good valve job and an "out of the box" port is only anout 300 cfm on the intake side.

Ok lets throw in that horrible chamber shape while your at it.

Bottom line is to make these a "race" type head wyou will have way more money in them than if you bought a good head like the SCJ, TFS street, Eddie etc.............. Then you port those and have something even better yet.

I know times are tough and money talks, but in this sport/hobby nothing is cheap.

From what I gather, if you have to go and do a bunch of porting to get them to work you would be money ahead using iron heads and follow the mad porter's instructions. Its not a cheap hobby but the iron heads would be more economical.
