the LT4 hotcam set has 1.6 RR's, and the 503 is compareable size to it.

The 503 lift with 1.6 would be 0.536"/0.544", 305 is 0.544"/0.544". The LT4 springs were made for the stock LT4 cam which had a lift of 0.498" and they were just suitable for the 0.525" lift of the hotcam.

Hey similar question guys, I have a mostly stock 97 lt1 formula, and i am looking to purchase a lt4 hot cam and the corresponding lt4 valve springs. My question is can the car run well with the stock 1.5 rr's or is it a requirement to move on to the 1.6's?
also are their other necessary mods needed for my lt1 to move well with the new cam and springs, thanks for the help. -D
