stock pistons or 836?

pat english
Does anyone have a source for cheap new pistons?i found these 836 pistons on ebay for around $120 bucks.here is the link:

http://www.ebay.com/itm/69-77-HONDA-CB750K-836cc-BIGBORE-PISTON-KIT-W-GASKET-/130712839062?pt=Motorcycles_Parts_Accessories&hash=item1e6f17a396&vxp=mtr#ht_1132wt_1030

the reason i ask is because im looking for some pistons around this same price but .25mm over stock.
I would like to do an 836 but am unsure if the engine will run right with just a bigger piston.do i need a new cam and head work/bigger valves for it to run right?

does anyone have experience with these piston sets from ebay?Anyone ever just install these bigger pistons and left everthing else stock?i ask because i have a small monthly parts budget of $400 and i want to get this thing on the road as soon as possibly.

I'm building an engine with that very same set right now. They are very nice pistons. Since, you will have to bore the engine to go 0.025 over, you may as well go 836cc. It costs the same for the machine work. Also the 836 kit is cheaper then 0.025 over pistons. You do not need to modify anything else to use the 836cc kit.

                 STOCK  1 vote   (even though stk.sucks Engines are great as is)

 69-77 K do you have a 78 ? If thoughs fit an 77 F2 I'd get them,but they don't.
  All your parts are no good so you have to get all new? 400 $ A MONTH THAT GREAT,can you try and do yourself ?How many miles on your engine now?Myself I'd love and will get A 836 kit when the right one comes along and hold till my engine needs to be cracked open ,If not I'll run her stock ,nothing wrong with them as is,just change oil and up keep.
  Try to be safe parts are not going to go down,as I'm sure most noticed.

                                               STILL STOCK eng.
