I would leave them. To make the changeover correctly you also need to replace 4 other pieces that are different to fit with the later "cool tin." > and one last question... after my first 1500 miles on the new > engine should i pull the engine and check the head studs?? and the > torque?? please let me know.. as i would much rather not.. but if > it is reccommended... i rather do it. I always torque the heads in stages, doing the last couple of lb-ft over a couple of days to let things settle in. With this method I never retorque. VW never recommended it, but sloppy assembly techniques might make it necessary. If you do the following I don't think it should ever be necessary: Flycut the heads just enough to clean up the seating surface Clean up the case surface enough to make sure that the new cylinders can seat on a FLAT surface Have case savers installed Torque to the upper end of the recommended range. - ******************************* Jim Adney, jadney@vwtype3.org Madison, Wisconsin, USA ******************************* ------------------------------------------------------------------- Unsubscribe? mailto:type3-request@vwtype3.org, Subject: unsubscribe
