Ok, I have the 420a 2.0 N/T. It's stock engine internal wise and I only have a CAI and complete exhaust system. I completed the compression test with all cylinders at factory specs. This motor has 120k miles. I'm impressed nothing has changed. No bent valves, and timing is spot on.
Now I'm looking at my lifters My oil pressure gauge reads 32-42 Psi at idle depending if I just came back from a drive. I'm noticing the common lifter rattle/tick noise when driving in the neighborhood. That's at 2200-2600 rpm. At 3k rpm. It's quiet. Other than that I'm noticing a major power loss. Its hard climbing hills even after downshifting. And pushing the gas pedal down on the highway.
No check engine lights what so ever. My vacuum gauge reads and shows no problems.
The only things I have left to do is swap out the stock lifters, are these lifters good?

buy a test pipe, the reason for this is because when the flanges were bought. the inside circle diameter was 2.4 instead of 2.5 on both sides, and what that's doing is causing too much back pressure.
Am I headed in the right direction? What else should I look at?
