i have a new style (1989 58cc open chamber) 305 set of heads, i cannot STAND the way a new style set of heads' valve covers look, but i enjoy the way the older engines valve covers look. My question is, even tho these are center bolt heads, and older valve covers run 4 bolts down the sides of the head, can i have the heads drilled on the corners to bolt up older style valve covers, OR will there be a clearance of the valves issue, or will it not properly seal? I got less than a month to have this done, so any help will be greatly apprieciated. [sm=helpout.gif]

check around i think there is i a kit that you can get to put the old style covers on there, and have enough clearence. And if not, if you are metal shaping inclined, makea platethat bolts up to the center bolt, then you can put older style covers on it, use like steel on aluminum plate.

hope this helps some what
