Common LS1 head gaskets? Could someone give me some common LS1 head gasket P/Ns, as well as their compressed thickness, and availible bore range? (Thinking of a 4.03 bore iron block)
Or maybe a link to a felpro catalog?

Re: Common LS1 head gaskets? i used a standard 4.0" bore 6.0L gasket on my motor. it's .030 over. no problems yet. and roughly 2k solid miles. i think the metal ones are .053 compressed and the graphite sets are .06 something. dont quote me on that though, it's just off the top of my head.

Re: Common LS1 head gaskets? ...thinking about the same deal...
I will likely go with a new stock LQ4 and 4.125 crank...I was thinking i could do this for around $4K ...wishful thinking?
Did you guys assemble your engines or did you buy them ready to go? Why?

Re: Common LS1 head gaskets? i built mine. you're going to need custom pistons and rods too. so by the time you're done w/ machine work, parts, heads, gaskets, bearings ect.. you're still looking at 5500 plus. i did my own heads, and used a factory crank, custom grind cam and still came just a tad over 2500 for a complete long block. which reminds me, i still owe the machine shop some money ;D

What is the thickness of the stock LS1 head gasket, The guy building my new engine wants to know, Melted the piston on my 5.3 so will replace it with a LS1, Also looking for a good mild blower cam if someone has a ideal, Will be a 377 with eagle forged crank and rods, j&E coated pistons 9.1, Dart heads, Comp 1.85 rockers, Beehive springs and rpm kit, Magna charger with 2.8 pulley with alky spray
