Quote: You will find that John will be right on top of any Stealth Head post. He just hates to admitt that they are good not great but will work for anyone that is looking for a up grade from the stone age of 906s and 915s.THERE are better heads out there for all out race cars. You will spend thousands more. I have a set from the first batch with valve spring seat pressure of 245 and open pressure at 585. I have made well over 100 pass's with zero problems. Can anyone on here guaranty that you will not have any problems? Heck no! You could buy a set of heads from any of the rest of the manufactors and get a bad set. One point that needs to be addressed is coustumer care thu.Thats the true measurement of a company. Ask John how many sets he has bought or put on motors that he built?
