Weight is a none issue with these covers, the pair of them may equal 2/3 lb. I guess I have them and can use them or sell them depending on how they look in the car.
On another note, this engine was a broken valve spring/dropped valve victim in a previous life and today after cleaning the rockers I found the intake rocker that must have been on the said valve. The valve end may have been salvageable but the pushrod end was pretty jacked. So I ordered a set of intakes. Probably the last hangup on this engine build (knock on wood). That and the cheapy dipstick tube is barely reading with 7 quarts in it.
