i want to know if it is just a better bet to just build a ls2.2 head and drop that on my lsj....or would that be bad.....if so would my best bet just to be lowering the compression of the 2.2 to the same as the lsj. and running that and just getting it tunned......

 

...moved to 2.2 section

 

the 2.2 head flows less than the LSJ head IIRC so I'm not sure what benefit you would get from that...

just build your stock one...
