The OP said he is running TF 270 heads which are max wedge port. But he said he is using a Trick Flow intake which is standard port size. So he is killing a bunch of power with the intake. Since he is willing to kill the power with the intake then I couldn't figure out why he wanted to pay a bunch of money for lifters.
The TF and Victor intake both work okay with the 240 heads but neither of them work very well with the 270 heads. For the 270 heads you have to step up to the Super Victor or an Indy intake.
We just ran a pump gas 505 on the dyno last week with 270 heads, a ported Indy intake and a Holley Sniper. This is a pump gas street driver going in RoadRunner. It made a little over 700 hp at 6200 rpm with a Comp Cams street roller camshaft and Comp lifters. We use the AMC lifter since it is pressure fed. Those are fairly inexpensive lifters but they work just fine in this application.
