Good Point BUT……do you want to run the risk of rendering that 365GTC/4 block JUNK?

Some Ferrari head studs screw into the block deck and others go down into webbing at the base of the cylinder with very long high grade steel studs.

As the blocks are aluminum and the studs are steel (two dissimilar metals)
‘electrolysis’ can take place over time between the stud and the block resulting in them bonding / seize together and effectively becoming one.

If your block has the long studs and electrolysis has taken place, when you try to remove the stud to rebuild your engine you could damage the stud or the block which would create a very expensive repair.

To repair this you have to drill out the broken stud or drill out the block and
install a ‘Helicoil’ or try to weld up the damaged area, so it can re re-tapped to accept the stock stud.

With blocks that have long studs going down into the base of the block, this can be very hard to do if not impossible and a irreplaceable or expensive block (engine) can be rendered ‘JUNK’.

By milling the deck with the studs in place and not trying to remove them
and using a special high speed cutter in the CNC controlled / programmed
mill you can get a perfectly level and smooth deck surface without running the risk of destroying a priceless engine block. Is it worth the risk of not using the latest technology available to us today.

Lesco Engine Machine in San Luis Obispo, Calif. know what they are doing.

 

Yes, if the stud's come out without a problem it can be
decked on a high speed mill after it has been leveled/squared
&set up off the center line of the crank journal. The sleeves
are removes before surfacing.
