Anyone in need of head work in our area should consider Mike @ High Flow Heads in Alsip il.

Super great guy, extremely honest, very sharp (Bob Madera approved) in business for the last 30 years, specializes in combustion chamber improvements.
The BBC especially suffers from a bad Combustion Chamber design and Mike does wonders to improve efficiency , fuel burn, power, and even better gas usage due to a better more complete burn and air flow.

Back in my Drag racing days I had an 5.7 small block LT1 (260-300hp stock @ the crank) With just Mikes work on the heads and a slightly bigger LT4 hot cam I pulled 400rwhp on the dyno. Unheard of back in the day.

100-150hp improvements with combustion chamber work alone.

My latest High Flow heads:
These have over 35 hours of just C.C. work .. partially due to the difficulty of working with Iron heads, Mike does prefer Aluminum, sorry Mike!












Dyno results to follow...

Looks nice! Good luck!

Thanks for stopping by. They are looking good

Good to know, Thanks.....looks like nice work.

So he stopped by and showed you his head(s)? Hmmm....starting to wonder about you Cigarette guys...

Did you have them flowed?

No he never did stop by. He kept them all to himself. So no need to wonder

That is a lot of patience involved to do that nice of a job. Probably why I have only ever done one set of heads

Holy cow, that's a work of art! Patience and Technic. I can only imagine what it looks like be hide the valves. Like he said, before and after results?? Very nice!

I did not have Mike do any porting of the runners. All I kept from the heads was the valves everything else was replaced so it was not in the budget.. Iron Eagles are pretty big head to begin with... I did not have Mike flow them.

Combustion chamber is where the most buck for my money was. The previous 3 valve jobs were sunken in pretty good and never blended in.. Probably 40 cfm right there. Piston hitting valve had to be adressed (not as much of a big deal as one would think) Back cut valves etc...

You`re right Andy, it is a work of art. To be able to see with a sculpters eye the work required, then duplicate it in 16 chambers and to have the patience to do all that ?? Mike is a dying breed , I don`t care what CNC program they come up with no machine can duplicate that kind of work..


Wish I had more before pics but I only took one:
