Competition Heads Part 2

Last month I made a post about Part One. Since then I have done 2 more sets of this particular combination with small changes tailored to cubic inch and cam size.

I'll pick up where I left off at polishing the combustion chamber. Then I CC the chamber to find the size and calculate how much to mill in order to get the desired static compression ratio.

Next the head is milled to reduce chamber size and ensure a smooth/flat gasket surface.

Time to set up the valve spring installed height, which dictates spring pressure and coil bind. This is very critical!

Install the seals and valve springs. Note the beehive design as opposed to dual springs. This is some of the latest in spring technology.

And there you have it! There is much more that goes into them that I didn't show in detail here. Port size, shape, bowl size, valve job angles and depths, flowbench testing and port speed, etc. These heads move over 280cfm @ .600" @ 28". Necessary to make 120,130,140+hp depending on the combo.

What A Week!

My flathead was weeping some oil out the headgasket, but I was pleased to see how nice it's burning with the tight quench. Usually these things looks like a coal factory inside. Shea has been trying to get his 650 Yamaha on the street but the carbs were more than he could tackle at 16, so I helped him clean/set them up! The weather has been extra crappy for this time of year but we still managed to get some good rides in. We had the largest group of bikes I saw on the flood run, which was really a lot of fun. I'm so glad my friends are so down to ride they don't care how shitty it is outside! Also went to see Willie Nelson lastnight which was really neat!

RIP Mondello

A customer brought a 113" street glide from iowa for me to tune yesterday. Upon arrival he informed me that it had Mondello heads and Joe had just passed away. He had been in contact with Brett Moore and those heads might have been the last that Joe did before he passed. It was kind of eerie and neat at the same time. The bike made good power with a broad powerband. Joe had scribed his name on the fin near the spark plug location.

Nice Jugs!

My wife went to vegas! If you ever get the chance to go, check out the HD cafe. They have quite a few bikes in there and some neat ones too, if memory serves there was even a Kmodel chopper! While she was away I machined these cases for 113" cylinders, from 3.750" bore to 4.060" for my latest chopper. I am concerned with the extreme power it is going to make so I welded this hub spacer in. This originally had a cush-driver sprocket, but will be solid mounted now. Holy SHIT! Plus that big inch mill is going to need some air, so a Mikuni flatslide fits the bill. Just be sure your air jet/bleeds arent blocked, you dig?
