So a friend of mine looks to be selling these kickass 6.2" Lentz Rods. They are SJ, billet 4340, come with Carr bolts ($400 alone) and weigh only 560g! Can you say Sweeeet! Furthermore I know this guy who is selling a set of kickass pistons, almost perfect for my application and super lightweight too. This setup will allow me to shave 2lbs of weight at the best possible place... At the piston, where it counts the most. (Reciprocating weight!) What this means is that I will be able to rev to the moon, and throttle response will be fantastic too!

 

As with everything, there's a small catch. Namely, the pistons have a compression height of 1.260" Which means that assuming a standard deck and a 327 crank, the pistons will be 0.060" out of the hole. This means that we want at least 0.090" of gasket space. Either that or we can mill the pistons 0.030" and use 0.060" gasket. Now my question to you all is the following. Can we stack gaskets on top of each other? If so can we stack different types? Is there a certain order with which they should be stacked? And what is the maximum height we can stack them? Keep in mind that this motor is not boosted (no Supercharging or NOS) and uses aluminum heads for a maximum compression ratio of 11:1. Are there any downsides to using so much gasket? Your help would be very much appreciated as I know next to nothing about the topic but I know that I want to run these parts!

first staking HEAD gaskets is a bad idea!

look here for the correct gasket

look at#011159 and #011069 copper head gaskets

 

CHEVROLET 265-400ci V8 SMALL BLOCK PRO COPPER Head Gaskets Gasket Bore 4.060 Thickness .093" special order thickness. To delete water passages add "NW" suffix to part#. Example: 011065NW. For 93 & up reverse flow LT-1 add "LT" suffix to part # Example 011064LT 011069

 

CHEVROLET 265-400ci V8 SMALL BLOCK PRO COPPER Head Gaskets Gasket Bore 4.155 Thickness .093" 400 Gasket has no steam between cylinders,Special Order Thickness. To delete water passages add "NW" suffix to part#. Example: 011065NW. For 93 & up reverse flow LT-1 add "LT" suffix to part # Example 011064LT 011159

 

and remember you may need two sets of intake gaskets to make it work/seal to the manifold and BTW this is the only brand of head gaskets I use anymore (they are that good and they make almost anything you can think of!)

BTW just spray both sides of the gasket totally wet with ( COPPER COTE) head gasket sealer and torque them in place on a clean dry block and you will have no problems on either aluminum or iron heads
