[QUOTE="davidd, post: 92156, member: 1177"] The PAC 512 titanium retainer is what I wanted to use. [ATTACH=full]20322[/ATTACH] There does not seem to be a big reason to use all the extra weight of the stock item. It was difficult to find the correct valve locks as the Ford uses tripple radius locks to keep the valve spinning. I did find a single radius lock, but it is not listed in their catalog, so it took me a while to find it: L8087. This means that you can turn a single groove into the top of the valve for a single radius lock. [ATTACH=full]20329[/ATTACH] For the top valve guide I turned down a stock one. I will have a few made up to fit the much smaller diameter of the valve spring. I did all of the above as a test fit to determine the design of the valve. The titanium retainer, 512, is $15 from PAC. I had to buy a new valve height micrometer to adjust the seat height and a new valve spring compressor due to the small diameter of the valve spring. David [/QUOTE]
