Cool. I'm very interested to see how this turns out.Ace, how do you measure the piston clearance? Considering you have the head and 2cv has the rest of it. Curious....
Thanks Ace. Same procedure with S cams?
He has to give me the measurement of how far down in the hole that the piston is at TDC, and also the thickness of the head gasket. Then I can know how far the valve can come down without touching. The cam profile will dictate how far the valve will be out at TDC, and I have a set of AVL cams in my possession, so I can get that from the profile.With the AVL cams intake valve only beginning to open at 9*BTDC, it won't be open very much at TDC. But, it depends on how high up the piston is. If the piston is not right up to the top, and we have a 1mm gasket thickness or something like that, we might have enough room.
I would also like to note that because of the similarities between the valves and chamber of the AVL and the UCE, all these same options can be available for the UCE too.So, if any UCE owners want a big valve kit for their UCE, and don't want cams or rocker changes, we can accommodate.
Ace,Could you indicate the anticipated ball park performance with this mod, along with the usual free flow and carb upgrades.
woah how much better would the upgrades be if you did the head and a 535cc big bore?
I'm VERY happy with what's going on so far & this guy (YOU, Ace) is just the best guy to work with that I've come across in a long time. We are SO lucky to have him & the Mondello guys. I hammered on the cylinder for a while this afternoon with ablock of hardwood & my 4 pound, coxcombed harley hammer. No luck. Dead arm. These guys ceMENT the gaskets in Chennai. Later tonight I'm going down & drive a putty knife in horizontally all the way around. That'll do it. Then the piston will go off to Ace to have recesses calculated & cut into the top for the huge beautiful new F-ing valves! Stay tuned
......The worst part is getting the old gasket off both surfaces; no gouges allowed). It stewed all night in carb cleaner, but that evaporates too fast. Goo-Gone is pretty good. Still a finger-killer job. I should have bought some acetone, but what do I do with the rest of it? Don't need it......
