your looking at around $2000 for these, it is done now and it is sweet, it is at the polisher and as soon as it comes back i'll post more pictures, yes you do have to mill the head off but this is pretty inexpessive and you have to do this to port intake side anyways, I have seen some other plenums but this thing is off the wall purty, Tons of thanks to D&J Precision
