you can get a thermal gasket for the IM, but it will not be cheap;however if i was already gonna pull it off and put the skunk2 intake mani on thats what i would do. http://www.hondata.com/heatshieldgasket.html
is one example
thermal gaskets are pretty cheap...i got one for about $30 I believe..a skunk2 one too.
if you dont extend the studs for the intake manifold you might not be able to tighten all the bolts or tighten them too far down, but mine held perfectly fine
Was about to say that^ gotta get extended studs. At least I did with my skunk2 pro manifold and hondata gasket on a GSR. A few studs were too short so it was either backing them out or getting longer ones
I didnt mean that the thermal ones where that expensive just more than the normal felpro ones at the hardware store, cause the hondata Im gasket goes for about 50 bucks.
