I was thinking of getting them when I get my heads worked. Does it really make a difference? Or is it just something that wouldn't hurt so why not? Just curious cause I'm trying to get everything I need now so I have nothing slowing down the job.

 

yes they really do make a differance in compression. im gonna use them. Lloyd told me with those gaskets and a 20 thousands mill ill be at about 11.3:1

 

Yeah its worth 10 or so hp on a decent setup(over 400hp)
