how good are the vmax heads?

[Black wing]

so i am getting ready to do a vmax build for my 91 and am trying to decide whether or not to get a set of vmax heads or just have the venture heads ported and polished up to spec. are the vmax heads about as good as they get or would i still be porting those up to get the best flow?

VMax valves are bigger. VMax cams are higher lift/duration. There is even some aftermarket cams for VMax and stronger valve springs, depending on how deep your pockets are! Check out PCW Racing, yes, the same people that make the stronger clutch springs for 2nd gen Ventures! I sent them a 1300 engine to have bored out and put in their racing cams onto the VMax heads that I sent with the engine, and their stronger springs. Complete rebuild, and dyno'ed and break in is running me a little over $5000 US but I guarantee you I will have one of the fastest touring bikes around...
