Currently installing an OVS race gas kit on my 07 M8. The kit came complete with everything I need, but Im having an issue with the head. Currently have an RK Tek head with high elevation domes which I don't believe will work, so my question, is there a certain year stock M8 head that I could get for cheap that will lower the compression enough? Or just suck it up, RK wants 230 bucks for a new set of domes.

I had a 2010 M8 with OVS Race gas kit. I used the lower compression head from an '09 for the first season, and then switched back to the higher compression the second season. I'd look for a stock '07 to '09 head to start with. I'd recommend calling Garr at OVS directly.

Good luck
