Honestly, I don't hear what you're describing.

Yeah i cant hear it either but i had a buddy with a ls6 swaped monte carlo it collapsed a ls7 lifter that had about 1500 miles on it. It wasnt excessively loud. It'd start out real quiet almost like the injector tick that the ls1s have naturally then would get noticably louder as the car warmed up. But it was never loud enough to hear from more than 10-15 ft away. can you notice exactly what side its coming from?

hate to say it but id pull that head and check the lifters.

hell go ahead and buy you a set of ls7 lifters, pull your heads get a 5 angle valve job and mill about .020 off, then slap it all back together...

thats what id do

that is the plan right now if i have to pull the heads. im gonna put ls2 trays ls7 lifter and i have a set of 5.3 heads im gonna have a buddy who works at machine shop do some minor porting and put my 2.00 valves in.

sounds like a solid plan man!

A couple other things id suggest is a set of arp head bolts or studs because you will have to buy new head bolts and the arps i dont think are much more but they are reusable in the future where as the stockers arent and you have to change them every time.

I just dont want to go through all the work and money and still have the same problem as now.

Man, I hear a little something in the video but it sounds more like an exhaust leak than a dead lifter; my laptop speaker may be to blame for that, though.

im pretty sure its not an exhuast leak since I didnt touch the exhaust and it didnt do it before.

I thought that cam needed 7.425" pushrods for unmilled heads

just went through the same problem. Order a comp cams pushrod length checker, The 6.800-7.800 will work. Check your pushrod length just as you normally would. Check multiple cylinders and both intake and exhaust sides. determine your length and don't let anyone tell you youre effing wrong. I had the 7.400 pushrods and ended up needing 7.500 but the people I talked to said I was wrong and that there was no possible way I got that length on stock heads,or my lifters were bad. The whole run around checking every possible variable. I was right. ordered 7.500 and it worked. Maybe you had the same problem I did. definitely check pushrods.

oh and my car is all stock heads/ intake/ lifters/ rockers

Yeah man, I would definitely agree than a cam over .600 lift like yours on a stock cylinder head (unmilled) needs 7.425" pushrods. $120 for some pushrods to me, is a no brainer for not having to pull the heads off again. Good luck, man.
