Well, on this particular head, the inlet port entry measures 38mm wide by 39mm tall.
Perfect for about 8500 rpm, which would never be seen by this engine.
Gotta wonder what these people at RE are thinking!!!??
At least the carb flange has a 33mm I.D. so we can actually use that part.
Anyway, the valve seat installation on this particular head don't seem to have much excessive overhang. Probably varies from head to head, just like we see on the Iron Barrel.
The valves seem to be the same diameter as the ones in the UCE. Chamber too.
We will upgrade these valve springs to do away with that strange AVL valve behavior at 5800 rpm.
The good news is that it looks like there could be a good fit for the same roller rockers that we use on the Big Head. This would be a plus!
Since I'm not expecting Tooseevee to be running around much at 8500 rpm, I'll see what I can get the guys at Mondello's to recommend about making this port smaller, for an appropriate rev range for this street engine.
Will need to raise the compression some. Will need to discuss this with Tooseevee.
Tooseevee's main goals are midrange torque, and easier highway cruising at moderate rpms.
Overall initial impressions are that we can help this head out quite a bit.
Port is crazy large. Valves are not.
Looks like a good candidate for roller rockers.
Piston may need changing if the valve lift gets too close to the flat top piston crown. Compression would need adjustment to suit the rocker ratio change.
Build quality of the head looks fairly good, compared to the Iron Barrel.
