185S frankenmotor

To start off I have a 1981 XL185S engine. Swapped 200x cylinder and piston. With an XR200 cam and carb. Went to kick it got stuck and bent a valve. So I had the piston recut and I had the rockers adjusted wrong so I bent another. So obviously no compression!! But my question is, will a XR200 head work good on this project? I know a 200X has a bigger combustion chamber than a 185/200. I'm going to assume that an XR200 is a little bigger than a 200x.

you might want to double check your valve timing. If the cam is 180° out that could be causing your issue. I'm not much into the 200's but I thought the XR and ATC top end parts were mostly interchangable.
