I'm in the process of switching combos but can't seem to find the right I.d locator needed for my Trick Flow twisted wedge heads. Here's a rundown. Valve springs are Anderson HR-20018 (170lb seat 590lb open) which have an i.d. of .805" Anderson recommends a locator part number tfs-2140040 but that locator is for a .570" guide. All newer style (made within the past 8 years from what im told) twisted wedge heads use a .505" guide, including mine which are in great shape. Called trick flow yesterday and they recommended a Crower locator of all things. Part number 68938-16. This one won't work either! Does anyone know of a locator that will fit a .505" guide, .805" spring i.d., and an o.d. size of 1.500 or 1.550"? Replacing guides are an option but pulling good ones out sucks too. Trying to run these springs with a 272/278* .656/.656" hydraulic roller in a 14:1 363" sbf.
