Default valves cover

Just wanted to confirm if the following tall valve covers (from summit) will replace the stock ones in my 1991 auto? Any one installed them?
And will they clear 1.6RR?

TIA

I have a set of cheap edlebrock stamped valve covers for my gen1 sbc, i used two gaskets to clearance a set of 1.65 ratio roller rockers successfully.

The thing i had to watch out for was the wiper motor...
On my car it sits right above the valve cover.

They will clear the rocker part, it's the poly locks on roller rockers that sometimes do not clear.
