I plan to replace the bolts with studs in the spring.

i did think about using studs. i opted for ample amounts of anti-seize w/ the factory bolts. this has worked well for me in the past.

these particular bolts were by far the worst i've ever had to work. the bolts really somehow became part of the aluminum head. glad that's over.....

I did the same with my new bolts... I actually think that I have more anti-seize compound than bolts in there at this time! LOL!

I hope I don't have a problem when I go to remove those then 1 1/2 year old bolts in the Spring. I don't want to go through that experience again!

Again, thanks for the excellent documentation and photos you are providing to the community.

Regards, Maurice.

i used anti-seize w/ my other motor with very good results. they backed out easily even after some corrosion.

this replacement motor was particularly bad; i think they degreased it & then didn't rinse off all the degreaser. it then sat on a shelf in a warehouse for EIGHT years....PLENTY of time for nastiness to ensue.
