Help with upgrading the TM VSR-10

[Ron-One-bullet]

Hi guys , first I'm apologize for my bad english.

Few days ago I bought TM VSR-10 G-spec.
I also ordered few updrades :
Laylax PSS10 Zero Trigger & Piston VSR-10
Laylax PSS10 Spring Guide VSR-10
Laylax PSS10 Cylinder VSR-10
Laylax PSS10 190sp Spring


The problem is that the spring was out of stock and accidenly they sent me the Laylax PSS2 190% Spring .

I dont know if the PSS2 spring will fit on my VSR.
What do you think ?

Another matter is about the Air Seal Damper Cylinder Head , can I upgrade the VSR without him ? if yes, for which results should i expect ?

Thats it , thank you guys.
Ron.
