Factory hydraulic roller LA cam advice

Any input on what a reasonable price for the head work to run a cam with larger lift on the stock 308 heads would be? My local machinist said it could be $1k + which surprised me. I was trying to keep the build under a reasonable budget but the project is quickly spiraling :rolleyes:
question: was that price just for machining the spring seats or more of a price that covered rebuilding the heads and the associated machine work?

for the one it seems like a reasonable number, for the other it sounds like a i don't want to do that price.
