6.1 Valve spring failure

Buschi340 said

are those the locators fitting the LS1511 springs? And need the shims as well.

Shims. Do i need all 3 different heights? Do I need them at all?

This is why I sourced my locaters, shims and seals from Thitek.

As far as I know, he gets the shims milled specially...which tells me theres no off the shelf solution

It saved me having to do installed height measurements as he knew exactly what thickness shim and locater was required.

We are lucky - the installed height on Gen 3 s doesnt vary much - if it did, each valve height would have to be calculated separately and we would use various thickness shims.
