Terrible seller, huge scam artist. Sold me a full "race head" ported and polished by a professional what a crock. Looks like a little kid did the porting. The exhaust side was completelt untouched. Said there were 1mm oversized valves, they were stock size. Head surface was scratched, and entire head had carbon build up swim around during shipping cause of the stupid way he packaged. Lashers and rockers were damaged also. Box was soaked in oil. He is a liar and a cheat and do not buy from him. When brought to his attention, he stated he would not do anything and that I should sell it to get my money back. Did a chargeback and will probably get my money back in the next few days. Took more than a month to ship it out cause he forgot he had a wedding when he promised to ship the item out.
