Just ordered your DIY guide. Looking forward to reading it. I'm sitting on the fence about doing the swap. I've asked a few indy shops in the DC area and both told me not to waste my money on doing the swap. One shop had 3 MB techs with about 100years experience between them and none had seen the problem. But now that I'm back in the SF bay area and have access to all my tools I'm thinking about a DIY. I like the weistec kit but damn they are pricey. My cost for a ARP BMW S65 V8 head bolt kit is nearly 1/3 that. I'll just assume the 625 plus material is really expensive ;-) Funny that wesitec aren't CARB legal (But that hasn't stopped me before) Like the head bolts are going to effect emissions....
thanks

If you opt not to use the water jackets than the studs can be installed with the heads on. Also studs are not required as the revised headbolts are plenty for a blower.

And by the way, if you're looking for a more in depth DIY (step by step), I've started a site (www.diytechnica.com) where you can purchase a more in-depth DIY for 10 bucks. But if you don't want to go that route, happy to answer any questions you may have about the process here.

Damaged cam!
I am in the middle of this job, myself. I’ve got the left side done. What prompted me to start tearing my beloved engine apart was a ticking lifter that never went away. I swore it was from the left side. All the lifters and cam lobes looked perfect. After installing the revised head bolts and lifters on the left, I moved on to the right. Opened up the valve cover, double checked correct timing, pulled the cams, and found the rear lifter on cyl 8 beat to hell and the cam lobe ground down. So, I ordered a brand new right side intake camshaft.
Thanks for this thread! Between here, Tasos on YouTube, WIS, and a buddy who is a dealer tech at Arrowhead MB in AZ... I got the information and confidence to tackle this job myself. It’s really not THAT bad of a job. Most nerve racking part is fearing getting the timing wrong and the head bolts snapping upon removal. I got all 20 bolts changed. Only issue I had with the head bolts was getting too excited and when removing the socket from the bolt, it got snagged on the head and disconnected from the torque wrench. The sound of a socket dropping INSIDE an engine makes your heart go into your throat. But, don’t panic, it cannot go anywhere but between the two head bolts and it is possible to get out with a little patience.
Thanks again!

Just wanted to update that I successfully completed the job. Had one snag to fix: I got the right side intake cam actuator wire pinched under the valve cover and shorted it out. This caused the motor to idle like **** (think ‘60s muscle car with a performance cam). I got the wire out and soldered it back together. Motor fired right up and is running perfectly. Valvetrain sounds better than when I bought the car two years ago. Glad to have my little beast back!

I havnt put the part numbers for the head gaskets as i not pulling heads.
So the final order would be
Lifters SLS - 156-050-02-25 x 32
M156 Updated Headbolt x20 156-016-07-69
Cam bolts x32 000000003236 x 32 - are these necessary (I noticed the original post didnt have them)
Actuator Bolts x4 910105-012018 - are these necessary
Timing Case Bolts x8 000000001150
Front cylinder head/timing cover gaskets 2x 1560162221 - i think these are the cam adjuster gaskets?
Valve cover gasket LEFT 156-016-25-21 - again can I reuse current one
Valve cover gasket RIGHT - 156-016-24-21
Spark plug gaskets for valve cover 8x 1560162121. - can I reuse my current ones?
O ring around spark plugs 8x - 013 997 23 45 - are these necessary?
Diamond Washers 4x 1560510275 (is this the bolt that holds the cam adjuster to the camshaft)?
Ill also do the pin flip for the cam adjuster while im at it.
Is it necessary to change the gaskets for the cam adjuster and valve cover gasket or can I re use my current ones? What about the spark plug gaskets and o rings?

Correct me if I'm wrong, but you'll be pulling the intake manifold off in this process, right? If that's the case, you'll need to replace those bolts too as they're TTY and shouldn't be reused. You could likely reuse the IM gaskets, but may as well replace while you're in there.

My plan is to get the head bolts replaced one at a time. I am trying to buy all the parts my mechanic will need.
After looking at the parts list I see that I might need 4 of Actuator Bolts - 910105-012018 and 8 of Timing Case Bolts - 000000001150. Can someone please explain what actuator and timing case bolts are? Does timing case mean valve cover? What is an actuator? Do I need these bolts if I am not pulling the heads off?
