OK I just need some information about this..


1- I am getting a kelford cam ( the drag one, I can get the Specs if needed).
and a upgraded valvetrain kit with dual springs.. AND 1mm bigger valves..( IF I can find them!!..

Q- will I have any problems With lash or ANYTHING ...I am gonna have a machine shop do the install, SO I should be fine ....RIGHT??...the SHOP should know how to clearence them ...RIGHT???
BUT I dont want to get it put ALLLLL back together and FIND out a I have a LOUD tick and have to take it apart again

thanks!

OH and where can I get a fair priced 1mm over valve kit.

ALSO ...does anyone know the spec's on a stock valve.??

This is the spec's of the valves I was looking at... ( I dont know if thay are any bigger than stock or not.....keep in mind I am looking for 1mm bigger valves!)

Stem Diam: 5.96mm
Length: 104.35mm

Yes, Thank you.
Now I know if the SHop screws up, I can fix it myself, without too many problems.

BUT I am still wondering if the specs on the valves I listed in the 1st post are bigger or stock size..I wasnt able to tell from your post..

thanks alot You have been MOST helpfull!!!

EDIT: I got it .. They are the STOCK specs that I have posted.

First off, you need "16" valves.. "8" Intake & "8" Exhaust Valves...

Ok, you don't need new buckets, just new shims for the proper thickness to properly set the tolerances for the new cams.. I actually already posted the chart with the thicknesses and part numbers.. Some guys will do the "Conversion" to put the shims under the buckets, I have this done on mine but i don't know where you can get those buckets, as Ron @ Axis did my head work for me and it was part of the package...

I "Assume" you have to buy "8" Exhaust and then "8" Intake valves.. Then you can alter the sizes.. As for the "Shim-less" buckets, I assume you will then need to purchase "New" buckets UNLESS the conversion that I have is "shim-less" buckets with Shims underneath them.. Again, I don't know what all was done there as I didn't do it..

LOL. you want it all. Low Idle and lumpy profile.. The two really don't go together well in a REX.. My idle is about 1500rpm and it definitely surges a little as the vacuum was totally crushed by my cams.. I love my cams however, nice power with my GT35R..
