Weren't the OE hoses known for being weak even when new? Repros IME (on another classic but for coolant hoses) are not really much cop for even short term longevity.

If it were me I would get some silicone items in OE black. On a number of cars it has resolved a number of boost issues despite the hoses looking great on initial inspection.

I have used Samco and Roose before with both being quality products, and Roose do give that personal touch with their service over the phone .

Of course if it is a stock garage resto you are going for then going secondhand may be your best choice. I know from Ford alot of bits are now NLA.
