I am at about 200 hours and would like to replace the springs, do a leak down and any other tasks. What are the recomended springs (brand, #) and what other issues should I be looking at??

Isky I heard are the best for this application (Via Tyler Crockett)

ISKY's are the best ,get their plus series tool steel thay will last for ever ,I think part number is 8005plus,,,in stock at 704-574-4020 cheap ,but your right on changeing them check the gold rockers also or best replace with comp stainless or pro rockers ,
