I would not worry bout the venturi bolt, try the long hard nose bolt it works very well. If you have a little more money to spend then try one of the new superbolts, very nice by all accounts but you will need some plastic nubbins to go with it.
Try to get an air system if you don't have one, a cheap(er) preset is a good buy.
