Why don't you just spend the money on a better cam? more lift won't help if the heads won't flow well to that high of lift.
1.7 on a hot cam will put lift at .557" thats not a lot, but duration helps much more than lift.

Sure he has to pull valve covers and swap springs either way, but it's alot less work. Also if it's a DD car then it's less stuff to go wrong and leave him without a ride for a few days.

Again....just me but it seems alot more involved to drop the oil pan partially, pull everything off the front including the timing cover...pull the intake....etc..etc.

The LT4 had hollow intake and sodium filled exhaust valves, with heavier LT1 valves the LT4 springs are marginal with 1.6s, 1.7s would be a bad idea with those springs.
1.7s are also going to be a hassle to match a cam to later when you decide to upgrade again. When buying parts always look to the future, you will save a lot of money and hassle. Buy a quality 1.6 the first time and it will be there when your setup grows instead of replacing them.

The 1.7rr will not only increase his lift, but it will also increase his duration about 2 degrees over the 1.6rr. So I guess your right duration does help much more than lift with his setup...
