Thread: Preload shims; where to buy

hi, thanks for the replies. i think we might be talking about different things. i am talking about the shims which sit between the heads and rocker shaft pedestals which are used to set the appropriate preload at the lifters during engine assembly

i understand the shims are the same from 3.5 - 4.6

The first answer to your post involved a question about which shims you were after.

I presumed swivels was a difference in terminology since 2x 15 thou has been mentioned as per my original query.

G`day ,

if you have trouble finding any you could makes them .

Most bearing type places will carry shim material of different makeups , brass , steel etc and should advise you if unsure how to work with it .

Use the base of one of the end pedestals as a guide/template because they have the oil hole in them and if you drill the holes , it will be easier to use the sheet as a whole rather than small pieces .

I have in the past used 3.5 inlet gaskets the factory ones not the aftermarket type .
