Does building the bottom end of a B18b effect the stock head or vice versa?

 

can you be a bit more detailed in what your asking? i just built my bottom end for my turbo setup and my head was not affected if thats what you mean

 

Im building a bottem end for a LS. Planning on going boost, but i dont feel the need to build the head and wanted to keep its stock. Im looking for around 300 to 350whp. Would that match power effect the stock head in a bad way?

 

i have a stock head on my built b16 makin about 300hp and when i had the bottom end built i just had the reconditioned the head ( stock build )

i dont rev past 7.5 ish since i have the stock valve springs if you want to be on the safe side i wouldnt rev past that

 

Make sense. Thx.

 

You can make 300-350 without building the block or head. although i would reccomend at pistons,rods.

 

But I highly doubt its gonna last with that much boost.

 

How much boost is he planning on runing? cause he hasnt said that yet.

My friend's ls has been boosted for 2 years makeing 325whp

 

depends on the parts. you can build either end without effecting either end to an extent.
