I wanted a set of full out eddy heads for an RB stroker engine. I called every head porter I could find from the Midwest to the northeast. I posted a thread about it. All the CNC guys use the programing from Modern Cylinder Head. Out of all of the head guys I called, NO ONE achieves what Jim Laroy does with those heads. I even had a local guy flow them and he was blown away by the numbers.
I ended up getting my heads, intake and roller cam from him. His knowledge, work and customer service is impeccable.
