LT4 LT4 header gasket

[AlHale]

Need help choosing the best header gasket for a set of ported LT4 using Shorty headers.
Any ideas? Having a hard time sealing the bottom center ports.

Speed Demon Motorsports here in Houston used Felpro gaskets on my long tube headers (Exotic Muscle) and so far they seem to be working with the Stage 8 locking header bolts.

I have heard of others using copper gaskets as well with good results.
