Referring to the new 25/30 and the Bentley cylinder heads to LeC.5350 and LeC.5367, will you kindly note it has been decided to use copper asbestos gaskets instead of the sandwiched type of Corrujoints, the reason being that the latter are expensive. This will also permit us to use the pistons which are standard in height. E/JNR.{Charles L. Jenner} | ||
