anyone think there will be any P to V clearance issues using those gaskets with stock heads that have been milled .010" and 2.00/1.56 valves and a stock bottom end
i'm not sure exactly what the lift will be on the cam yet, i'm in the process of having a custom cam done
reading up on quench area i think those gaskets will put me right into the ideal (?) amount of ~.051" quench

anyone? TTT

 

Your squelch area will depend mostly on how far down the pistons are in the hole. If the bottom end is stock, they can be down quite a bit. In this case even a thin gasket won't help you.

But on your original question, the LT1 from GM is a non-interferance engine. This gives you a ton of piston to valve clearance for even radical cams. If your worried, mock it up with light springs and clay on the piston. Rotate the engine trrough a cycle and measure your clay. Unless your going nuts on your cam you shouldn't have a problem.

 

I ran a CC306 with that gasket and heads milled more than that with no problems. The thing you need to worry about is not really the lift, but the duration. That is where you might run into interference.

I'm also using these gaskets with aluminum LT1 heads milled .030" and a CC306. No problems whatsoever.

 

thanks guys! looks like i'm gonna use them
where did you all order them from? Summit?

 

just for clarification, this is the correct part number for that gasket...... P# MRG-5716?

 

I would use those gaskets as long as you are going N/A. I had a little trouble with them with Nitrous. But, the problem may have not been the gaskets.
