Inputs on H/C/I package instead of just heads and intake.
Inputs on H/C/I package instead of just heads and intake. Long story short, I don't know the specs of my cam, so I am looking for inputs on where to send my 243 heads and get matched heads, intake, cam, and valvetrain.
Since I am getting a new cam, P2V is no longer an issue, so I can get bigger valves and/or have the heads milled more for higher compression.
So, my main question is larger valves vs more compression... which is better for 1/4 mile times on a daily driven LS1?
Larger valves will likely be TEA stage 2 heads.
More compression will likely be AI 226cc heads, maybe TEA stage 1.

I was leaning torward AI, and since I am going flex fuel, my tuner recommended going with higher compression. So, I am going to see what high compression heads and cam specs can be done.

I am trying to figure out if there is a "sweet spot" between 243s compression and cam. i.e. 10.6:1 and a 230ish cam vs 11.1:1 and a 220ish cam.
