Hi as the title states, I cut the valve guide down for more seal to retainer clearance.
This is on a set is 193 heads.
Now I have a problem ( I guess i always did, I just didnt measure)
I used a Howards cams cutter ( Just like Comp Cams) to lowered the guides 5mms and the cutter narrows the diameter to .520" , flexible positive valve seals fit fine.
I left majority of the guide base intact.
Problem I found is both my Alex's .500 lift spring kit and the factory Ls beehive spring are too big for the bases.
Vortec bases measure out at .880 diameter, the TBI bases are .754
Vortec uses a single spring. Tbi uses the same spring, with an internal dampener.
I had thought I could use the vortec springs or the beehives.... because the TBI uses the same vortec spring.
Guess the factory cut the bases down for the inner spring.
I've looked at ID spring locators, but cannot find one that has the ID of .520 and an OD of .880
( I can finish cutting the valve guide all the way down to make the ID .520 instead of the .754)
but then the locator is also .60 thick, so it adds height back into the installed height.
My thought was that I could have a collar or sleeve made up. ID of .520 and OD of .880,
so it would be about .360 or 9mm thick.
But then I would not have to way to secure it to the head/ assembly--- maybe a tack weld.. if you can even mig weld cast to mild steel?
Anyone ran into a similer issue or can think of a possible solution?
possibilty something like this and drill out the center to fit?
