My heads on my 97 trans am motor has been decked twice for a total of 0.025. What head gasket should I use? It's bored 30 over also with xr282 comp cam and scorpion 1.6 rockers

 

Let's move this to the correct "tech" forum - LT1 Based Engine Tech.

 

Anybody?

 

What is your target static compression ratio? Have you checked piston-to-valve clearance?

 

I haven't even built the motor yet just got the block done but I'm needing suggestions on what's a good compression on this build and what head gasket would work with it, as far as clearance not checked yet, but going to.

 

Has fact block deck height and fact stroke height has just what I mentioned above.

 

Fel-pro 1074.

 

Thank u much

 

On jegs sight it says
"They have oversized wire rings that lock into receiver grooves which must be machined into the cylinder heads. Precise machining is critical to the success of these gaskets".
Is this true do I need machine work to use em?

 

You don't need any machine work to use those. I have used them on a couple builds with no problems.

 

Ok thank you

or if you need more compression and P to V is good the GM B-body iron head gasket is .029 thick

 

What would you guess my compression to be with my set up that I posted above? And what's a good compression ratio to get the max hp out of it with no power adder? What if I did want to add power adder what's a safe compression ratio?

 

We can't guess without knowing what pistons you have...or are going to get. For naturally aspirated applications you can easily use a compression ratio of 11.5:1 to 13.0:1 with a proper tune. If you want to use nitrous be at the higher end of that range. If you're going with a turbochrger or supercharger the stock 10.4:1 or lower is probably a good plan. If you're going with a low pressure system you can stick to the high end of that range, for higher boost levels you'll probably want lower static compression ratio.

Since you already have the cam chosen, maybe you should give them a call to see what they recommend...

Good luck!

 

Ditto. Fel-Pro 1074 for the LT1 works just fine for stock heads. My heads have been decked at least 0.003" and I'm using them with no trouble.
