Any of you guys out there in Cad power land know how much the valve centerlines were moved side ways of front to back compared to OE heads? I already have some custom pistons set up for 2.19 int and 1.88 exh. in the early style Iron heads. When I get a set of these Boogie man heads I figure I will need to recut the valve reliefs , just curious how much and in which direction the valve were moved. I can guess but thought I would ask if some one has already been down this road. Pistons now will allow for .700 lift and a good amount of duration for future exploits.

I have boogieman heads from Potter. I had to enlarge the intake valve relief on venolia pistons from CadCompany that originally were made for iron 76cc heads. The intake valve is moved over towards the exhaust

CadCompany sells those heads. Courtney is The Man of these engines after market components. The people at CadCompany are very helpful.

I kinda figured they had to move the intake over toward the ex side ,also if ex valve location was adjusted also ?just trying to get idea of how much I will be modifying my new pistons from race tech. I called Cad Company but did not get any numbers from the person I was talking to. Just that the pistons they sell will work with either style head. My pistons are set up to allow around .750 lift but were cut for stock location 2.19" intake on OE heads. I will wait till heads get here and do mock up , checking for witness marks and go from there. Let you know how it turns out.

The intake valve locations required an offset rocker arm.

I have remembered that I didnt like Potters 5/16 studs holding the rocker shaft assembly down to the head. I bought the 7/16 T&D rocker assembly hold down studs and counterbored the rocker shaft pedestals for them. Now it fastens like the T&D equipment. Also machined ends of pedestal for button head bolts to keep ends from flexing under 600 lbs open pressure.

On what? I have R.A.S unit on a Kruzik component engine. The boogie man heads from Potter when he was in business used a version of the T&D iron head setup. The chromemoly shaft support is the best setup of all the rocker components for the Cad500. The T&D units are The Best.
And$$$$$$ 1500. Now. Now that Im on this forum Ive been readin all the othe posts from over the years and see that a lot of you guys are hobbists of the top order also. Its been interesting. I put up some videos of Cad500 engines being test srnd run. Cad500 C460 intake is one. Cad500 billet crank is the other.

Cad500 4.6 billet crank was second one. I run em on stand with water and big fan to keep em cool. Other people I know bring their freshened engines and load em on the stand to check that alls well before the back breaking engine compartment installation. Lots of fun. Last picture is C460 fabricated to Cad500.

Was curios as to why you aren't running a one piece rocker shaft.
Heres a stud mount rocker arm setup I fabricated last autumn and winter. 120 cc heads.

On the aluminum heads.

Alway thought stud mounted rockers were better, not experienced with Cad engine but did have problems 401, 425 Buicks. Never a problem with Ponchos.
