Thread: fitting headers

G`day Wells

Either will work fine , the single gaskets ( 8 of ) are a pain but work fine .

Later model ones can be bought that are one peice per side ( 2 of )

If you use the singles make sure they go on the correct way , the bolt holes can be lined up either way but the gaskets only seal one way .

Silicon that is high temp rated is fine as well just have to be a bit careful it doesn`t get wiped off when fitting .

If they`re new , they were probably supplied with new bolts ?

If not you will probably need new ones as some may be too long and also the heads of the bolts may be too large also if they don`t have locking heads , spring washers will be of value in the long run .

It`s a good idea to be sure all threads on bolts and in the heads are clean and have no burrs or such .

The main thing to watch out for is that you don`t cross thread any of the bolts and of coarse you don`t break any when removing the manifolds .

I had them on my 4.6 classic. I wouldn't recommend them, they are far noisier than the cast iron manifolds for very little useful gain..

That's why I sold a new set I had to LRH.

They make more noise for little gain. Efi manifolds work well. I use silicon, seems to last.

I seem to recall from the book on tuning Rover V8s that the EFI manifolds are pretty good.

Re silicone, my local LR guys use it, too.
