Author Message   eric Posted on Sunday, November 03, 2002 - 04:24 pm:    How much should/could I shave off the heads of the 3.9 heads, to retain stock or better compression ratio, if I use composite gaskets? How much "meat" is available to remove before you get into trouble? Thanks eric   jp Posted on Monday, November 04, 2002 - 07:17 am:    Does your 3.9 have shim gaskets now or composites? If composite, you dont need to skim them. If shims, check the manual for skim limit (dont recall right now) - there is a head thickness check point diagram, showing min thickness.   eric Posted on Monday, November 04, 2002 - 11:41 am:    It had the metal shim gasket. It is a '90.   hendrik Posted on Monday, November 04, 2002 - 04:38 pm:    http://www.rpiv8.com/engine-6c.htm   John Moore (Jmoore) Posted on Monday, November 04, 2002 - 08:31 pm:    Did you try this post on www.roversnorth.com BBS? That's where I remember seeing this discussed.   eric Posted on Tuesday, November 05, 2002 - 01:31 pm:    posted at RN, no response, yet.
