Which heads?

Finally able to reply to everyone. My phone is acting crazy. If I mill the heads .040 how much do I have to mill the intake? Thanks
There is a formula in the MP books. I do not have it on hand or in the memory.
276/288/114 advertised;
218/[email protected]
.441/.441lifts
"Fair-smooth idle, low-midrange power. Works with stock-2,000 stall, 9:1 and higher compression, and gearing."

the only thing small about it is the lifts.218/228 is a nice size tho.
I e used this duration before a have found it really good and best with 3.21 or better gearing w/stock to slightly bigger tires. IDK how it would work with a 2.96 or 2.76 gear. Maybe a bit sluggish out of the hole.
