I pulled out the new EMPI GTV-2 Cylinder Heads to prep them. I’m so used to dirty filthy heads (at least with the ones from the AR, AH, and AJ engines, that a brand spanking new 0 mile head, even if it is EMPI, is a nice thing to hold. There have the larger stainless…

So the universal cases have the opening at the bottom right next to the oil pump area where a Type 3 dipstick attachment would go due to the differences in the way those engines have to sit in those frames. The new engine hardware kits that are available come with a small plate, gasket, and…

Now I’ve been hesitant about attempting this mod for weeks now. Hell, I event debated about it yesterday. I don’t know if it was the perfect case tapping going to my head or what but I blew out the debris and measured things again. I started the long tap through the lifter bore and stopped…

I feel far more confident to do internal case mods and material clearancing by hand these days and I intend to do several to the AS41 case. Planned Case Modifications Case – Interior The interior of the 1/2 side of the case receives the most modifications and will include: Enlarging the main seal return oil…
