For prevention of breakage of the engine I think, to replace bolts of a head and lifters. What lifters is better to choose, (for the standard engine) (514 HPs). I think to establish lifters from a black series of SLS... who what thinks ?Or after all , better standard lifters of SLS! what difference between them?

 

Those look like they will fit fine in an L6 M603.

The M113 Lifter is housed in the rocker arm with little margin for aftermarket upgrades.

If one were to billet a true mechanical tappet cam we could rev higher but tuning is our friend here.
The culprit with the hydraulic lifter in the rocker arm is the oil bleed shim wearing out. I think you have to buy a new rocker to get the shim.
Oh Well, Happy lifter hunting.

Thanks for wishes!

 

To do this job you will need to remove the heads and it has a lot of labor time involved. Also do the head bolts since they have this issue and the normal SLS valve buckets are just fine the difference is the coating i believe. I am doing the same to my car right now. You will also need new gaskets since the old ones can't be reused.

 

Here someone wrote me that bolts of a head can be replaced, in turn without removing a head! 😑

 

You can, but not everyone will agree it is an acceptable way to do it.

 

But what think of such way of mechanics or engineers, it will be correct, in respect of a design, Concerning reliability of installation.

 

It's been done more than a few times. I haven't read of anyone having problems with this method. I wouldn't hesitate to do this myself if I had a m156.

 

If it is possible so, then it is necessary to try! Thank!
And as for composition of material of which ARP hairpins are made, they are combined with aluminum Blok m156? In comparison with bolts from SLS!
