FZ block need to work with the head abit. About compression you can squishband the head or the block. Mean lower or machine the block or head abit (either one). Some ppl no put gasket between the block and the head, but they just apply some gasket sealant only. This also can slightly increase the engine compression. But for daily ride dont get it too high compression ba if not will sacrifice engine durability. But for FZ block piston i think you shall shave the head abit just too lower the head down abit to gain back some compression lost due to the crater on the pistons. Since now you using 60mm block i dont think you will get that kinda Horsepower on the 57mm block unless you change to big head valves and done some port and polish on the head intake and output holes. If all this is setup and tune nicely. You will achieve more than you previous horsepower. Carbs 26mm is just very nice for daily use ler. Unless plan to play drag than can opt for bigger carbs. The last thing is you need a very gooding foreman to do it nicely.

Bro, this is the advice i got also....
Since I already have FZ block,just do this cheaper than changing 62mm uma block.....
Last few mths was wondering why my bike not much difference from standard.....

But the foreman tell me the fz and lc head is exactly same...>< So i dont think need to ply the head if 57mm...But for 60 above i think it was necessary
LC head and FZ head can not be same oni similar....
Even a lot of ppl also say FZ cam same with LC but again not same but similar in some ways....
There is different but can not really c if do not measure....
If u say same the more u need to do the head, bcos 1 is 54mmm and 1 is 57mm, rod not the same...
You oni think of head and block, what about stroke?
60mm and above if u say use big valve i agree la....
Added on August 18, 2011, 11:28 amsome foreman oni estimate only base on theory, have they try and confirm the results?
Pomen tat got try u ask them chain, or watever use how much they know...bcos they try....
