bird55, I just sent a PM to you. Please let me know if it doesn't reach you. 

55blacktie, Thanks, no one was hurt, thanks for asking.
You can find some explanation of the work done on a blog I did years ago with some pics and the dyno sheet. I did post along the way on this site but I'm sure most of those pics links are broken and I'm not sure how to find the posts easily.

You can look here

bird55, more detailed information for your build would be appreciated, but I realize it wasn't yesterday. It sounds like you had it done by the right people, at the right time. 

I'm sorry to hear about your new Bronco. I hope no one was injured. 

Take care.

BlackTie, I am very happy with all the work that John did and his recommendations for what I was only setting out to do. It was a "Street" port job. Mummert also installed new seats, valves, etc., and measured out the ISKY spring pressures.

Since the insurance co. recently declared our new Bronco Sport Badlands a total, I have been driving the old bird for all our errands. I don't usually do this, So now that I am driving it more, it starts quickly and runs and drives well for an old beater!

The extra work and time I took back then to get what I wanted has been well worth it. Even though at the time I kept worrying about the costs. I remember thinking I would never spend the $325.00 for a Blue Thunder intake, that's outrageous. However, I did. I wish I had bought ten. Back then an iron B manifold was only around 10 to 20 bucks or so.
Ted also helped me immensely. with advice and support. Jerry Christianson was the first to get me started. 'Nuff rambling.

Thanks Joe. I am satisfied with them, as I spent quite awhile working on them. The only thing I never liked was how the valve seats were installed. The edges seemed to protrude into the combustion chambers, but they were done before the heads came into my possession. I didn’t know if that would have any negative effects.

If you are happy with them, then that is all that counts.  Pictures seem to be Ok.  Everyone has to start somewhere in the Hot Rodding business, and you can take pride in saying "I ported them myself".  Good luck.  Joe-JDC

Joe,

Thank you for the information and the photos. I had assembled my G heads over a year ago after doing some amateur porting myself. I took some pictures of one of them. Would you be able to comment on them? I am hoping to assemble the motor in April. No problem in disassembling and reassembling on my end.

If you take too much out of the exhaust port roof you will find water.  Same for the floor.  A simple squaring up of the port will help, but most of the flow increase will come from a larger exhaust valve and multi-angle or radius valve job.  I have seen completely round exhaust ports on the Y block heads, D shaped, oval shape, and square.  I try to get 70% flow bias between the intake and exhaust port's flow, and that is difficult with the Y iron heads.  Here are a couple of shots of the texture in a combustion chamber that I found in my archives.  Joe-JDC

Great info, but I remember reading somewhere that the "bump" in the exhaust port at the manifold should be left there. No?
