Trust me I ran the numbers between selling these and going with Aluminum many times but in the end it was still thousands more and then I`d still have a stock head without Mike C.C. work.
Mike does not charge by the hour, I`ll look at the bill and get you a better number but it was not $3K .

Last time I posted a discount code for RedHorse and the same thing happened.
I posted this because I have a LOCAL guy who does great work , has great prices and is the most honest guy you`ll ever meet so I thought I~d share. THE END!
Don`t worry about my cam, my flow numbers, my set up, I have that under control but thanx for your concern. WTF

Why would I pull out perfectly good cams? How would you custom grind a cam according to combustion chamber work? Ground a new cam because I gained 40 cfm , there was no port work done. Changing cam specs because of this work would be a complete waste of time and money. I don`t care about the air flow numbers, if you do Mike will be more than happy to flow them for you.

Something to keep in mind. Icdedppl did NOT bring these heads in, just because he wanted port work. He brought them in, as he had some leakdown issues, and some extremely tight guides. He wanted them gone thru, as in rebuilt, as a preventative maintainance kind of thing. The chamber work, was a add on.
Before we get wrapped up in flow numbers, we must remember, that cylinder head basics apply no matter what cam is used here. No backcut on the valves, poor transition in the seat/bowl area, is not helping airflow. Would you opt to leave the obstructive transition, and uncut valves, based on what cam you are running? No, you'd say, clean that $hit up and backcut the valves.
As far as the chamber porting. Unshrouding the valves to the gasket bore, is not a new trick, but effective. That was done, along with some cleanup and blending. There were several CC's of volume added to the chamber. Which will slightly reduce compression, but the airflow and burn quality, should more than make up for the loss.
Another area that was worked on, was valve spring setup. They changed out the springs, for more spring pressure, as the lifters icdedppl has, call for more spring pressure, per both John Callies (morel), and Bob Madera. Bob and Mike from Hi Flow heads worked together on getting the proper spring for the application, as to choose a spring, that not only has the correct pressures, but the correct distance from coil bind, to try and prevent any kind of spring surge.
Overall, I know what was spent on these heads, and I think it was very reasonable for the work done. They are nice castings, even though they are Iron. To get into 2 sets of aluminum similar castings, with CNC ported chambers, bare, Dan would be looking at 4,000 dollars. Then you need to buy valves, figure in another 1000 bucks. He may have been able to transfer his valves over, but either way, it still would have been quite a bit more money to convert to aluminum.
All in all, I think he's got a nice set of heads there, and should see a bit of improvement over what he had, when he dropped them off. Mike at Hi Flow heads proffessed to me years back, that bbc chamber work can provide great improvements in head performance. As you see as of lately, when you look at a brodix or AFR head, what a CNC chamber version does compared to the as cast version, to me its a no brainer to opt for the CNC chamber option, when purchasing those heads, for the additional cost, if full cnc isnt in the budget.
