Permatex #80036(34A) is what I have at home.

My final fine grit was 600 if I remember correctly and it was oil based. Some like the water based better because it cleans up easier but I couldn't find it in the grits I was looking for. I bought mine from a place near Yorktown, VA over the internet that does motors for cart racing (small motors).

looks like the last head that i did was for my personal car and i used permatex 765-2657. i just called them up to find out what grit it is and they said it breaks down to a 220. Hmmm i thought it was alot finer than that. i guess it was fine enough because the engine gets good compression and runs hard when you step on it. where can i pick up a finer grit like the 600 grit vettenuts is talking about
