Ok, here is an update and its VERY important. The gaskets should be here by the 11th, if not sooner. That is the official ETA.
Pricing went up...for next year. I am waiting for the actual thicknesses available (.050 is .051 as an example). I do know .051 will be the thickest of the cheapest pricing. .056 to .075 is the next range, and .080-.098 is the thickest.
Pricing will be updated so that the current price shows as a sale price and the thickness selection will show the price differences.Ben

yeah reading owned me. these would payoff in the long run.
hold the price for a few more weeks please. still working on what i talked to you about the other day.
ok reading the pages for the 3400 and the 3500 gaskets, it says the 3500 cometic ones are 3.72 and thats close to the 3400 stock size. i know the 3400 cometic ones are smaller diameter. now with that said i could use the 3500 cometic on my 3400 right. might get a 3500 bottom end down the road.Last edited by geldartb; 12-15-2009, 08:50 PM.sigpic

Wrong gaskets?
I got the 3400 comtic mls gaskets for my 3.4 iron head as directed in this thread. I went to install them but the don't line up with the bores and the embosed parts hangs out over the side of the block. The sticker on the package says they are for LX9, lZE, LZ4 92.5mm 0.030"
I did some reading on the LX9 and found out the bores are offset 1.5mm from the original 60V6.
Was I sent the wrong head gaskets?
