W5 intake manifold gaskets

Hello,

where to buy w5 intake manifod gaskets?

It seems that the Mopar P5249466 (.060") is N/A or "discontinued part".

P5249432 (.030" )Thin ones is still for sale??or is it??
( i can't find any w5 part numbers from the MP catalog.)

how about INDY 360-1 gaskets, or should i go with "trim to fit " gaskets. Any advices?

Heads are cnc ported and intake will be match ported/ported LP w5 intake.

Thanks
