I currently have the cheap 50mm bbk fro ebay that comes with a matching head.

It needs to be rebuilt will this small upgrade fit without any problem. Hitting the valves or anything?

So the place i got it from said their are thicker gaskets for the 52 and that he's out of stock on them. Any one know where I could find a second base gasket or the thicker ones i'm hearing about. He said it should work fine but I think he's just trying to make a sale.Yea life would be simple to go scrappy. It would also be simpler to have the money to go scrappy too.

It will work with one gasket but the compression will be too high would be hard to start and your crank won't last long. You can get an extra gasket anywhere eBay, scrappys, partsforscooters. I did it with one gasket and compression was 240 psi the starter wouldn't crank it and I busted my cvt case kick starting it. When it started it was a beast but not worth it you'd have to Jump it off a car anytime you shut it off.

Right that was with a Buford big valve head. your ebay head won't have near the compression that the buford head had so it may work, you can try it if you don't mind taking it apart if it doesn't work.
