Will this gasket http://store.summitracing.com/partde...5&autoview=sku
fit an lt4? I'm looking for one of the thickest gaskets on the market.

Stainless steel...33 dollars.

copper...127 dollars

Both fit LT4.

 

Do they make anything thicker than those two? thanks btw!

 

The 1074's are probably going to be your best buy. I am getting them. Why do you want it thick?

 

I cannot replace my stock bottom end, and I need to drop compression inexpensively for a blower setup.

 

What CC are your Heads?

 

Take caution in using this approach. Because a head gasket does not perfectly match the bore you will end up with an area between the head and the block that will be prone to hot spots due to the sharp edge created by the mismatch. This "void" will have a negative effect on quench, disrupt the chambers ability to have an even flame front and promote detonation which is exactly what you don't want under boost. It would be better to stick to a gasket like the 1074, pulley the blower down to drop boost and spend time getting the right tune in it. The end result will be the same power with a much more effecient and safer motor in terms of reliability. Just my $.02
