Valve Cover Question
I have just finished polishing the Plenum & Runners on my engine and would like to add polished or chrome valve covers. I checked with the dealership and through their performance parts division the following valve covers are available for my 86 L98:
12341671 Chrome Tall Valve Cover
Chevy small-block V8 valve covers: tall, with baffle, w/Chevrolet-Bow Tie logo. 1959-86. Two covers per box. Licensed part by GM.
More information available at: http://www.gmgoodwrench.com//perfpar...382§ion=ep
Should I go with short, tall, baffle, or no baffle?????? What's the difference???
The ones mentioned above are tall with baffle and look fine to me will I have any problems installing them??? Will they clear the rockers with the baffle....because I think the ones without the baffle have been discontinued.
Thanks

I'm told talls interfere with the runners.
THe easy fix is to use stock style stamped steel, roller tipped rockes for about $50 a set and then yoiu keep the ratio and fit under short VCs

I just replaced my valve covers on my '86 so I might be able to help. Tall covers are if your car has roller rockers. If your car is has stock rockers you want to use the short "standard" covers with the baffles. The baffles help keep the oil drip or flow over the rockers. Below are the covers I finally bought and I love them. Also, is your '86 a Early or Late? Early models have iron heads and the late has Aluminum heads. The easy way to tell is the cover bolt pattern......Aluminum heads have the four bolts going down the center on the covers and the Iron heads have two on top and two below the cover. I hope this helps.

You can look elsewhere for valve covers.
You have a SBC... meaning you can buy dress up parts pretty much anywhere. Autozone carries a nice selection of stuff actually... at least my local one.
That's where I'm planning on buying my stock height polished valve covers.
