Default question for the engine builders

If i mill my heads .050 do i need to mill the intake also, i have done this before on fsb and if you mill the heads you will need to mill the intake 50% of the heads, so this would be .025 for a .050 milling on the heads, is this true for ls1 heads.

milling 98 5.7 heads .050 to get a cc close to 60 and cr of 10.5 on my 01 4.8L.
Thanks

milling the 98 head .050 will just put you back at the chamber size of a stock unmilled 4.8/5.3 head.

You don't need to do anything with the intake. My heads are milled around there and the intakes I've used sealed fine. (ls1, ls6, ls2)
