DO NOT BUY EDELJUNK!!!...i spent $2000 on a set of performer RPMs and had to get $600 of work to make them useable...the casting was brutal...twisted ports, not eve .050 on the ports....and edeljunk didnt help me out of exchange them whats so ever..there was so much flash, valve grind was nasty, and there was even 1 sticky valve...
i also had to get them resurfaced, out of the box, they werent "true"
i will never buy a set of edeljunks again....take a look at the link on my website.
