240zip Posted November 2, 2006 Share Posted November 2, 2006 I have a L28 F54 block that's been bored .5mm over in which I installed flat top pistons. I've searched the forum and it appears this set-up results in the pistons protruding above the deck .021". I measured my #1 and #6 pistons at TDC and they were indeed .020" above the deck. I have a NAPA (Victor) head gasket on order. I believe it's a 1.6mm thickness gasket. The head being used is an E31 head. As far as I can tell, it was never shaved, but has been completely rebuilt. I'm using ARP bolts (main, rod, head). Any recommendations on gaskets? The set-up is what I'd term a mild street engine. Headers, Triple 42DCOE-8 Webers, moderate cam, etc. Quote Link to comment Share on other sites More sharing options...
z-ya Posted November 2, 2006 Share Posted November 2, 2006 A stock L28 has a deck height of 0.030", so with less height (0.020"), you should be fine with a stock gasket (1.6mm). Also, a stock L24 with the E31 head has a deck height of 0.080", so even with the E31 head, you are OK. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted November 2, 2006 Share Posted November 2, 2006 Stock gasket is 1.2mm, isn't it? Crushes to something like .052" I thought... Quote Link to comment Share on other sites More sharing options...
z-ya Posted November 2, 2006 Share Posted November 2, 2006 I just checked, and you are correct, stock thickness is around 1.25mm. I just ASSumed from the previous post that stock was 1.6mm. From what I know all stock and stock replacement (except FelPro, 1mm) are the same. Quote Link to comment Share on other sites More sharing options...
