I'm in the process of installing the Toda C cams in my '99 si head/'00 B18C5 block. I also have a mugen two layer headgasket that will be going on as well.

The head was milled once when it was taken off the car the first time. A Spoon two layer headgasket was used and never had a problem.

I took off the head again, sent it to the machine shop for cleaning, and valvespring/retainer installation. They said that milling the head again was not necessary which was a relief.

But will I still have clearance issues? I couldn't tell you how much was taken off the head the first time, nothing major. Any help would be greatly appreciated!

 

probably not, but get it clayed if you are worried

 

haha ofcourse I'm worried, but I would think it would be ok if the old cams worked fine with a thin headgasket?

 

if youre worried ill trade ya my bs
