T1 lower cooling tins, how?

[JIMP]

Hello

I have a T1 engine with a tuned length header, because of this the back cylinders -flywheel side- exhaust tubes run not as usualy do the heater boxes below the heads but kind of diagonally exactly below the pushrod tubes, also they run higher -they almost hit the pushrod tubes. I'm in the process of building a std t1 cooling system for this and I need some advice on this lower part. The std lower tins can't do the job as they are, so was thinking of using the std under cylinder tins, use the front small vertical tins and for the back to keep the std tins but cut very short, just to make a vertical path for the air, in this case the complete lower part of the pushrods will be uncovered but still the air will be directed to the lower part of cylinders and heads also. Also as the air will blow directly on the pushrod tubes will keep away also the heat rising from the exhaust tubes. Do you think that this will be an eficient way to cool or I should consider another way of doing this? cheers

Just trim the J-shaped sled tins, so that the headers will fit nicely.

Don't be too concerned about the cooling air underneath...the air that blows down between the cylinders and around the outside of the cylinders has already completed it's cooling job, by the time it hits the sled tins.  By then it's just on its way out the back, past the pipes/muffler...
