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.
