1973 225 valve adjustment help!please!

well im new at it so im probably wrong about it being accurate ,maybe im just a little chicken of firing it up with the valve cover off and sticking my fingers where they dont belong lol, anyways it sure sounds tons better and i hope i havent created more problems by messin with it .....

Trust me it's not that hard. I did it for the first time not too long ago and as long as the idle is low it's pretty simple. I also just bought my first slant two months ago so I know how daunting it sounds....the hardest part was getting use to trying to get the socket on while the rocker while it was moving. I still have all my fingers!
