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?

 

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.

 

...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?

 

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
