Ok, bad news for me, I dont know if any of you remember me asking about valve spring shims months back, but basically I didn't know they existed till me head was put together, they are manley springs with bc 272/272 cams, the answer i wanted to hear is the one I eventually accepted, which was "it will probably be fine"
Anyway, the car rattles at 2800 rpm and up, (video at bottom)
At idle if you rev it up you can hear it, while driving it only makes the noise when I apply more than cruising pressure on the gas pedal.
I believe it has to do with the bc springs and not having shims, plus the head was machined. (If someone thinks its something else, let me know)
So now what my plan is, is to take the head off while it's in the car and install shims (I dont think I can do it from just removing the valve cover, because the valves would need to be all the way up to reset the springs in place)
Now I dont have the equipment to measure what size shim to get, so if anyone has run this setup with a head that's been machine, let me know what worked for you.
The other thing I'll do if possible, is drop the oil pan, unbolt rod/piston 3, removed it and do new rings and gap them correctly this time, I actually gapped ring 2 a bit big, and that cylinder has 130 psi compared to 175 on the others.
Let me know if you think this plan will work, or if there is any better ways to do this.
Thank you guys for the help in advance
