*edit*
Do you mean the cutter uses the head and valve guides as the fixture? Oh, ok. Gotcha.
That's not so bad; a far bit better than pulling & disassembling the engine...
So, it's only the price of the cutter bit, then?
yea there was just a thread about this too so try and search back a lil bit and u can probably find it bc it aint ut a few days old ok the tool is made by ISKY so you can probably just buy it from summit or there site itself
