Update!
Okay, we have finished Roeland's head work, and it is ready to ship!
The package is basically as described previously, and it is the most affordable Fireball package yet!
Basically, we did the previously described porting and head mods, and also have included a "beta prototype" set of UCE rockers which were done in a similar fashion as the Ace Shotgun Rockers for the iron barrel kit. So. this package includes the head work AND the ratio rockers for the same price as the Iron Barrel Fireball head work alone.
Close to .500" max lift with the rocker ratio we used with the STOCK CAMS in there! No specialty cams needed to buy!
The Ace beehive springs and valve gear will handle that lift.
The max flow in the port is almost identical with the max flow in the iron barrel Fireball, but the lifts are not the same. We used more lift in this UCE to get the max flow we were after.
We used a valve size which allows more lift, with using the regular flat-top piston he has in there, and (hopefully) will have sufficient clearance over TDC, but he is going to have to check it, and maybe there might need some small clearance adjustment. And maybe it might be just fine as it is with the flat top piston in there. We'll see.
So, we went with more lift, and not the big valves, and that's how we went at it, in the final analysis, for this first one.
Stock chamber on this one, for keeping it affordable.
After we get some reports from him, we will see if there needs to be anything changed to reach what we were after.
So, we finally have one going out, after all this time, and I'm very pleased about it!
