RE: 318 Poly Help
No problem, man.
Craig Fountain makes finned aluminum valve covers for 'em, but he's in Australia, and although you can get 'em through a few distributors (like Gary on the 318 Poly Yahoo group) they're still about $400 or so. Hall, Edelbrock made a 3x2 and a set of finned aluminum valve covers for 'em back in the day, and the intake is $400 - $500 nowadays, and those original finned aluminum valve covers have gone for as much as $800!!!
Most guys just have 'em chromed or do the crinkle coat - it's cheaper by far, and you can put that money into some go-fast parts.
Seriously, check out those two boards I mentioned - especially the Yahoo one (which has pics, speed secrets, tricks, etc).
