Re: Valve tip to rocker arm alignment
Doug, Thanks for your input. I never thought of elongating the mounting holes to help the problem a bit, although then they would all be off somewhat. You make it sound as though it is quite important on stamped steel rocker arms to maintain good alignment for things to last. This car will only be driven 1000-1500 miles a year and is a pretty tame unit but I hate to half a$$ anything especially when it comes to durability and longevity.
Keith, yes new GM guide plates are still available @ $6.30 ea. wholesale. Part# 3860038 for 3/8 GEN IV. Unfortunatly they come 5 to a box so you may have to buy all 10.
