Hi All,

Just a few pics of my 'Job for the Day'.

Currently doing an engine rebuild so whilst my headers where off I decided to give them some LTC.
Sandblasted and resprayed - $50.00... I supplied the exhaust paint... $20.00 Bursons.

I also heat wrapped the headers, for i really want to keep the engine bay cool. Bursons and Repco wanted $105.00 for a 15 meter roll of heat wrap, no clips included, though i knew I would need more than 15 meters for a pair of heads, which meant i would have been up for $210.00

In the end I found a good contact online, which i collected form Seaforth. $70.00 for a 20 meter roll which also included 10 S/Steal tires. I also brought another bag of 10 tires for $30.00, which i did not regret. I also brought 8 heat socks for my plugs for in the past I've always had problems with arcing and shortlife span on my leads. Heat socks cost $12.95 each... Repco was wanting $21.95 for Top Guns.

Wrapping the headers took longer than I thought and it was an intuitive process. I began buy cutting the roll into 2 equal lengths, than smaller strips for the individual pipes. My advice would be - better to have a small off cut at the end of your run than coming up short.

At the end of the job, i had about 2.5 meters left over. I wrapped the headers tight but not over the top. Bottom line - 15 meter roll would not be enough.

This is the link for the heat wrap - http://www.thermalvelocity.com.au.

His an older guy working from home. Product comes from his son's factory in England. Product appears to be of top quality... and needless to say, I m just your average gear head - I do not work for this company!!! BUT - Highly recommend.

Be interesting to see how much heat reduction you get from this.

I agree with the quality of the Thermal Velocity plug boots. I recently put 4 on the drivers side bank of my EFI Windsor with 40p heads and ELGT Headers. It was a bugga to get them on over the plug boots of the Ford Racing 9mm leads I used. Cylinders 3 and 4 are resting on the header, so time will tell how well they stand up to it.

It would have been a mission to heat wrap the headers, props to you for doing it, it looks like you did a really good job.

Just an update... Heat wrap instructions informed the headers will smoke for the first 10 or 15 minutes on start up... though the last thing i wanted was smoking pipes on a new engine start up.

Cure - I stuck a heat gun up the end of the pipe and sat it under an extraction fan... and sure enough,they smoked like an old indian

Colour also faded back to a mid tone grey/black.

Finally, for some strange reason I thought I would be able to pick up the pipe without gloves, after 10 or so mintes on the heat gun. NOT SO - gloves required. I mean it did not burn my hand when i picked it up, but there was no way i could hold the pipe for more than 5 or 10 seconds without gloves.

So now I am starting to think - how much heat reduction will actually occur ???

you must have a pretty good heat gun.... I use an old hairdryer which I suspect wouldn't of sufficed lol

I had that wrap on my extractors in my 6cyl. for the purpose of the argument the heat wrap worked well at reducing the under bonnet temps.

Hard to find a solid answer but some say it reduces the life of the extractors due to them loosing their ability to cool themselves. Mine are still kicking and they've been around since before pacemaker was pacemaker & still serve me well.
