    Revshift Motor Mounts with Headers

    I've been reading lots of threads on different MMs for the first gen V and I am leaning towards doing the Revshifts. I have the car torn apart and waiting for a header install right now and decided I should do them now while ive got the exhaust/cats out of the way. Anyone have any issues with header heat on the Revshifts? I read reviews after a few hundred miles - just wondered how they were working after 10k miles or so? Any need for the silicone heat jackets?

    Can they be installed with headers in place? Kind of forgot to order them and wanted to put the car back together today so I can hear the exhaust...will i kick myself later for not doing this all at the same time?

    Go with the Revshifts. You need heat jackets if you're running headers. You cannot install them with the headers in place. You will kick yourself.

    My only advice is to support the engine with a jack at the front lip of the oil pan, where it's strongest. Also, use 6-point (hex) sockets to minimize the chances that you'll strip something. In my case, I think I just have a really, really stuck bolt and it wouldn't have mattered whether I used 6 or 12 point.

    Re: Revshift Motor Mounts with Headers

    I swear I tried searching for threads like this on both this site and LS1Tech. I found a couple, but not that specific one. Thanks for pointing it out.

    What does the "juice" in the stock mounts look like? I havent taken mine out yet, but they dont *look* bad from what I can tell. They have 87k miles on them and while removing the stock manifolds/cats, i noticed what looked like rusty water "spray" under the mount and on the subframe. Cant find any rusted metal, so I was wondering if it was the prized mojo fluid in the stock mounts?

    My car rocks at idle and has all the other tell tale signs of bad mounts which is why im replacing them - was just curious.

    Go with UMI mounts and never worry about replacing them again, never worry about heat shields again.

    Thanks, but i already ordered the Revshifts. My somewhat lofty goal is to someday build a stroker to put in this car at which time ill upgrade the mounts. This motor has some miles on it, but its got plenty of life left so ill run it for a while.

    Yeah, I'm sorta thinking of stroking my LS2 at some point too if I wind up keeping this car for a couple more years.

    Mine looked like burned tranny fluid and stank to high heaven. You could take that two different ways and both would be probably be accurate Anyway with the heat shields in place it is pretty hard to see that they are damaged but they likely are.

    Need?

    I'm about to install Kooks 1 ⅞ and use DEI titanium wrap with lava rock technology. Still need jackets??

    Revshift claims the heat-related damage that could occur without jackets is cosmetic. Since you are wearing two pairs of underpants (speaking figuratively, of course), you'll probably be OK. If it were me, I wouldn't use jackets.

    If you read my writeup, I never used any sort of heat shield / wrap, and I've been good so far. (knock on wood)

    When i talked to revshift they said to get the heat Shields. I'd rather spend the 40 bucks on some gas, but i really don't want to do these again anytime soon so it's cheap insurance in my mind
