I have a set of Jet-Hot LTs on the way and have a few questions that I couldn't find answers for. I'm pretty sure that I'm going to use 1" stainless ARP header bolts. I've narrowed my gasket selection to either the Felpro 1406 or the Mr. Gasket Copperseals. Where is a good place to buy O2 extensions? I'm not sure whether 12" O2 extensions are long enough, or if I need the 24" extensions. Also, I can't remember if there is an alternator bracket that bolts to the stock manifolds. If there is, can it be bolted to the headers, or do I need some sort of spacer? Finally, does the stock oil dipstick tube still work or are there any modifications that have to be done there.

Thanks
Andrew

 

they r alterntor bolts on the manifold and its a bitch to get back on. i left mine off u got 4 alternator bolts on it. so u can do without that one. yes the stock d[pstick works fine. i made my on 02 extensions its pretty easy. and have fun putting the LT on its a bitch

 

my LT's went on like a piece of cake. I agree with travis on the alternator bracket - I didn't use the one that goes to the header bolt... there are plenty of other bolts holding on to the alternator in my opinion. I wouldn't spend money on O2 extensions - it's very easy to splice wire in - plus you get them just the right length you want them.

 

Thanks for the advice. I can't wait to get everything back together.

 

you will like the LT it picked my car up 3 tenths in the 1/8

 

use the copper seals. remove altenator starter dipstick and ANYTHING in the way. moving the A/C compressor forward helps too. Remove the steering elbow on the driver's side.

 

don't use copper seals. i used them on my car any they leaked like crazy, my headers were used but i ordered a set of Percy's seal for good gaskets and they are great no leaks at all with them. recommend them 100 %

 

i agree percys are great and reusable.

 

what about napa OEM metal gaskets?

 

I have OEM gm gaskets,im installing my lts and whatnot this weekend so il let you know how they work
