Does anyone know or have a part number on a set of valve covers that will clear roller rockers and not hit the heater core box an ‘85 442. I’m getting ready to do a motor swap and the motor has tall Rocket Racing aluminum valve covers and I’m afraid they’re not going to clear without modifying or deleting the box.

Factory covers will work but may need double valve cover gaskets or valve cover spacers. Other than the very tall fabricated valve covers, Edelbrock chrome covers and Chinese chrome covers, few exist new. The M/T, Hardin and Edelbrock aluminum valve covers that have no baffles clear but are no longer made. The last set of Chinese chrome valve covers I bought at least 10 years ago leaked and rusted but. There are a taller version of the Chinese chrome valve covers available.

These would work but are very pricey, would look awesome but you would have to wait for Offy to do their once a year run.

These are affordable Chinese tall chrome covers.

Thanks for the information. These are the ones I have now and I love them but I really don’t want to lose or modify the box.
Nice 350, what are the specs? Those are extremely nice but extremely tall valve covers.
Old school cam, make sure you have enough stall. Using the 2004R? Of course it would need some upgrades.The stock D5 is rated at 2400 rpm. What carb are your running? The Street Demon 750 or modified 800 cfm Qjet would work great with that motor.
Hopefully they put enough clearance if they used the Speedpro forged pistons, the directions are wrong, .002 instead of the .004" minimum needed. Did they mill the Edelbrock heads? If not, you will be around 9 to 1 compression. Not trying to be negative, just trying to make sure everything goes smoothly and runs they way it should.
I'd run a quick compression check on it to see how much squeeze it has. I get nervous anytime I see "Mondello".
The motor was already built and ran. It was in a ‘72 Cutlass and drag raced. The guy tore it down to freshen it up and put a hydraulic cam in it and decided to build a bigger motor so he put this one up for sell.
I run stock valve covers on my 455 in my 79 cutlass I cut the baffels on one set but the last set I just dimpled where the nuts were in the baffle until it fit I have no clearence issues with my box
