I recently noticed that my stock talon was heating up quickly, one leakdown test later my headgasket was found at fault. I bought some felpro headbolts and used a new composite headgasket (looked generic imo) that was given to me. Anyways I had done a cold compression test right before I pulled the head and got 155,140,140,160. Well after the headgasket and timing belt but before installing intake manifold, exhaust manifold, ect...I decided to do another cold test for kicks....good thing I did my cold numbers were insane...125,105,105,110 dry and 155,140,140,155 wet....so now my wet numbers are pretty much where my dry numbers where before...odd...so to my question, what am I missing here and what could cause that? I'm open to input, I'm kind of hoping I'm just having a brain fart, I pulled the head again and I'm ordering some arp studs along with a felpro permatorque hg, a combo Ive had no issues with on bastard 20g talon. As for the torque specs maybe I got the wrong one ??I went 57lb/ft, loosen, 15lb/ft, 90degrees, 90degrees on the bolts but when removed the newer headgasket looked as if it had been clamped 1/3 as much as the one I took off on the edges.. Ideas? Hopefully I'm just newbing out LOL...

Honestly I didn't, I know I should have but I assumed it was fine....I even had the feeler gauges just needed to get a straight edge...I'll def be checking warpage this time to be sure of if it needs attention or not. That could very well be the issue but I didn't consider it to begin with
 
Well after checking warpage it seems to be .007 between 2&3. Off to the machine shop with the head... While I was at it I figured I would check the block for warpage and I didn't find any but I managed to fail yet again. I've been on a streak of making dumb mistakes and it sucks, anyways I bought a new pack of razors to clean the blocks deck... I reached for a blade and got to cleaning, a second later I realized I had two scratches on the deck. I had not grabbed a new blade but an old one with a burr right next to the new ones. How does that happen, face palm. Anyways the scratch doesn't catch my fingernail but if I go over it super slow I'm pretty sure I can feel it. I'm hoping a permatorque can have its way with that scratch so I can forget about it and call it a day but I'm sure I'll hear otherwise LOL. I've never used copper spray but would anyone advise it in this situation? Thanks for the help.
