To delete water passages add "NW" suffix to part#. Example: 011065NW. For 93 & up reverse flow LT-1 add "LT" suffix to part # Example 011064LT 011062 and YEAH IM USEING THESE WITHOUT (O)RINGS FOR YEARS WITH NO PROBLEMS http://www.chevytalk.org/threads/showflat.php?Cat=&Board=UBB64&Number=239142&page=0&view=collapsed&sb=5&o=&fpart=1 Quote Link to comment Share on other sites More sharing options...
pparaska Posted April 16, 2003 Share Posted April 16, 2003 That last link should be: http://www.chevytalk.org/threads/showflat.php?Cat=&Board=UBB64&Number=239142&page=0&view=collapsed&sb=5&o=&fpart=1 BTW, in that thread, I found someone listed a .028" composition gasket by Mr. Gasket. Summit lists it, but you should be able to order it from alot of places. http://store.summitracing.com/product.asp?p=4671&SearchType=ECat $39 (each?) Mike, As I remember, the deck heights I measured on your shortblock were .007 to .017" down in the hole. .028" gasket would be a good fit. You'd have from .035 to .045" quench height.

Mikelly Posted January 21, 2004 Author Share Posted January 21, 2004 Now that I've got my heads back and I've found that they have been resurfaced, taking .004 off, which head gaskets should I be looking for... Mike 8) Quote Link to comment Share on other sites More sharing options...
A. G. Olphart Posted January 22, 2004 Share Posted January 22, 2004 Mike- Maybe try Pat's calculator to see what difference .004 makes? http://members.uia.net/pkelley2/DynamicCR.html Oops... you need to cc the buggers, don't you- that isn't a thickness change over the full bore diameter. (Or you could figure the chamber area at the head surface and go from there). How's the surface finish on the heads? Quote Link to comment Share on other sites More sharing options...
Mikelly Posted January 22, 2004 Author Share Posted January 22, 2004 Surface Finish is like a mirror! They did excellent work. Mike Quote Link to comment Share on other sites More sharing options...
