It's pretty, I can't argue that but... In some cases pretty isn't best.
I don't know if that timing cover is polished aluminum or if it has been chrome plated.
I haven't had personal experience with them either. From what I have read over the years, the chrome plated timing covers leak everything everywhere. Considering how the chromed water necks leak, why wouldn't a chrome timing cover do the same ?
If there isn't any plating on the mating surfaces, no worries. If there is chrome plating on the mating surfaces, good luck with it.

well the chrome stuff is triple plated the gasket part is not plated the water neck is billet alum that we just polished it out factory ones most are alum. holley fuel pump , water pump is prw racing one they higly polish out tti c5 headers pulleys are mopar triple plated chrome motor mounts are mopar triple plated, no the wreck car went to another guy he got itfrom the wrecker company this is a 69 340 block 4inch callie crank , eagle h'beam rods diamond pistons comp cam, milodon gear drive, main bearing girdle kit , arp engine fasteners milodon pan and windage tray edelbrock rpm heads crane adj rocker arm airgap intake done in durshine all the ignition is going to be msd stuff msd pro billet dist, 8.5 superconductor wires ballastercoil motor is all polish inside oil passage are enlarge trans is 904 case 2.76 low gear , 5 clutch pack , bolt in sprag , turboaction j converter mopar new triple plated deep pan turbo action rev.valve body all redline clutch and kelvor bands rear dana 60 4.10 gear brakes 4 wheel disc brakes willwood just going to be a cruiser, i just like my chrome for the color comb i had it done in black but there was 9 duster last year at the shows black /black/ and black stripe so i change mine to black /red/ red stripe i just want to be differ ,like i dont like the black wheels but alot of folks think thats the stuff , thats makes the world go around . top and bottom of the car is slick all new ........everything trying to get her done the red one needs a sister /or brother lol thanks guys trying figure what rims i am putting on
