Remove it, straighten it, strip it, and either paint it or have it powder coated. Get new heat insulators also.

I cut a piece of aluminum matching the shield and pop riveted it with washer spacers on the back side. More efficient that the asbestos they used.

You know...this topic of insulation for heat shield refurbishment has been discussed many times. Don't know if its in the Library but an advanced search (which searches archives) will yield lots, including many pics.

Was interested if anyone had used something other than aluminum for shield, aluminum gets hot quickly, something that would radiate heat away from carbs completely.

Many of us have one of these and there's many discussions on here about them.



Convertible: CKD 11/66 first registered 8/5/67. Owned since 3/77. 90% original sheet metal. 18GB +40 balanced with almost all new internals. Peter Burgess big valve fast road head. Piper 285. Fidanza FW. Basil's followers and pushrods. TR7clutch. TT exhaust. ARP everywhere. 123 ign. Needham 4synchro c/r box.. Stock rebuilt/replaced suspension. Superpro bushes. New brakes all round including all pipes in SS flex. Interior redone. CAMS approved roll bar and side bars. Lots more. Hybrid of o/e and show/fast road car. Not for sale - it's my toy!

GT: UK car built/sold December '78. Stripped back to bare shell (with extensive bodywork to come). Powered by 'worked' Rover 5 litre V8 (ex TVR Chimera) with efi. T5 box. FC IFS. CCE rear attached to Salisbury axle with Quaife. And a whole lot more to yet to come. Stealth is the word.

I was told SS transfers heat , not radiate away ?

I will agree with Barrie #8. I run a polished stainless heatshield and have had no problems in the very hot conditions where I live.

It works well, looks good and is easy to keep clean.

I cleaned and painted mine with silver high heat pain. and intend to install header wrap on the back side. I think Dick Morris suggested this a while back.

Paul's heat shield I linked in #6 sits on top of the phenolic spacers so if stainless transfers heat then it's further away from the manifold than a stock heat shield. You don't have to buy it but you did ask for an "upgraded SU carb heat shield suggestion". He does one for HS and HIF.

FWIW I added small heat shields either end of the head as in intense heat and stopped in traffic I suffered vapor lock. I don't believe that happened because of Paul's heat shield rather the conditions I found myself in. Since doing so no further vapor lock.

Stainless steel holds heat longer and faster than steel. It's very anti corrosive. A very abrasive metal to machine or grind. I would stay with the stock heat shield like Dick recommends and give a good cleaning and hit it with some high heat spray paint of your choice or powder coat it. People choose stainless so it doesn't rust.
