how do i know if the block is a22r or 20r block? and is the block worth getting checked to be rebuilt?
The block should be stamped on the drivers side, at least the '84 I just rebuilt was. If it is a 22r block and it isn';t cracked or there is no unrepairable damage to the cylinders, it should be rebuildable. If the crank can't be turned, you can buy new cranks with bearings for a couple of hundred and your core.
should i look for a 22r block and stroke it with a cam i want a power gain while remaining reliable for a daily driver occasional offroad ripper... i just don't like down shifting to 2 or 3rd to pull a hill... also any clutch recommendations? if not the rebuild any suggestions for an Dr Jekyll and Mr Hyde transplant? 
id like for it to pull up to a stop light and the evo next to me think im running a v8 after i spank the doors off his matchbox weedeater 
Generally speaking, a 22r series motor can pretty much only be built to about 145hp and still maintain its stock turn key reliability, while one built this way is an improvement, it isn't going to blow the doors off any evo at a light. If you want a reliable "sleeper" you will have to do an engine swap.
