Valve Cover SBC
I have a factory SBC 350 in my 72 C10 and replaced the valve covers several years with a kit that I got from Summit. Tied of the look and want to replace them with the factory covers. I was looking at my old ones and was wondering a couple of things.
First of all, if I get them powder coated, will they hold up to the heat and will they seat with the gasket and not leak? Second, I really like the look of what Chevrolet did on the VCs of the SBC 283 where they scrolled the word 'Chevrolet' on the top. I see decals that you can buy, but I was wondering if the covers for the 283 would fit or do they make the same valve covers for the 350? Also, do the decals work and withstand the heat as well? See attachments for examples. Thanks

Re: Valve Cover SBC
The 283 covers may fit but some had staggered bolt holes....the other issue would be the PCV.......the old motors used a different crankcase breather system and the valve covers have no holes to attach the PCV valve.

Re: Valve Cover SBC
I have these, but in silver. Get a lot of compliments about them.

Re: Valve Cover SBC
Staggared holes: I think it was 58 or 59 and earlier valve covers were staggared.
Later ones also had the chevy script on them. Repro ones are still available, I think, check c1 and c2 corvette parts vendors. since your goung with non correct valvecovers anyway. Have thought of the early corvette finned aluminum valve covers? They always look very cool. Good repro's there too.. pricey but about the same as a doctored up powdercoated ones. |

Re: Valve Cover SBC
Don't forget the original 283 vc's with script won't allow you to add oil either unless you have the intake with the fill tube!
