most times not needed,I do use the VP that has the heat cross over blocked with the alum intake and carb to keep the heat soak down.

rtv in the corners and across the end rails lightly.

the good part is,it is reusable a couple of times for fast intake/carb swaps.

some times the gaskets can be to thick,so check with member 'topside", he sells some thinner gaskets sets that are cheap and good quality.

member "road hazzard" has a nice brand of gaskets that he makes as well,great non-stick gasket compound,IIRC

congrats on your new 6-pak set up!

you will need tires soon
