swapping heads
Hi im looking at getting a recon pair of heads for my 99/00 classic and was wanting to know if the heads from any other versions will fit.
Thanks for any advice you can give.

You need to speak to Wurzel Gummidge. 
Seriously, the phase 2 MY99/00 ones have a different IM bolt pattern to the MY93-98 phase1/1.5 ones, so you need to fit MY99/00 ones to keep all your ancillaries etc.
To that end, the best heads you can fit, without any unnecessary ballache, are the STi 5 and 6 ones. These have underbucket shims and come with free-breathing cams and are good for high bhp - IRO 500bhp (or maybe more???).
