well roy has over 8 gallons of testing with his spacers between him, glenn, and other friends of his. Everybody had one thing in common, engines lasted longer and never gave any problems. Its been done on at least 5 known engines and there was no problems. Im pretty sure if something was going to go wrong he wouldnt have told anybody. Roy wouldnt sells something he wasnt sure is 100%.
