Poly Engine what was good/bad about it and why is the LA better?

Can somebody post a shot of an assembled poly engine with the stock valve gear without the valve covers on?

I had a 64 Dodge 440 2 door sedan for many years. The poly 318 had gobs of low end torque and made a great solid driving engine. A friend from Vancouver Island BC used to drive down to Seattle for Mopar Drags at Bremerton Raceway and the back-to-back Spring Round-up car show in his 63 Plymouth B-body. He drove hundreds of miles to get there, bolted drag radials from the trunk and ran 13.00 super consistently all day, often winning the days bracket race, then swapped tires and almost always took his class at the car show the next day, then hundreds of miles home. The engine? 318 poly with dual quads on the factory cast iron manifold.
