i already have some exhaust wrap for it,and the carbs will be fully enclosed when the bonnet is shut.also with the carbs constantly drawing air in there will be a flow of cold air inside the box to keep the tempratures down, so i dont think that will be a problem but we will see.if it doesnt work i can change it.
i am trying too find a manifold but i want to keep expense to a minimum so im really looking at second hand parts.
the conversion wont be undertaken for a while anyway so it will give me time to sorce parts
