Hello Chris

any QR 2.0 head should be OK but there were some revisions to the inlet port through the engines life so its best to try and match the same year if you can and check the overall width and height of the ports when buying compared to your part

the 25 head is no good as the combustion chamber volume is different ( bigger) so you'll lose compression ratio and power

its safe to use this head but probably not what you want
