come on honda guys, tell me what you think. ANY opinions are appreciated, but yes, I know it's an LS.

how much better does a b18b head/IM flow than a b18a?

Awhile ago I started a DIY port/polish job on a spare b18a head from Ebay. Well, it quickly turned into a polish only when I realized my dremel knock off just wasn't up to the task. No big deal, but I have been aquiring some of the necessary gaskets, ect. to do the head swap and when my "b18a/b" IM gasket came in, I noticed that the holes in the gasket are considerably larger than the ports in my head. MY question is, bigger ports=better flow? Maybe I should "rebay" (I love my made up term) my b18a head in favor of a b18b, and polish that one?

I've heard rumors that the IM flows better, but not the head...suggestions? Oh, my future setup, all the parts are laying on the floor, is:

polished head
IM/EM port matched if possible, not sure what header
Gude stage 2 cams
springs/retainers
upgraded ECU
blockguard(future nitrous use)
DRAG high comp HG

on a b18a 92 teg LS

 

yes b18b head is better than b18a head . b18b flow is better.

 

Hey buddy I know you from HondaHookUp. You got a couple responses on this topic there if you havent seen them.

 

just out of curiosity how hard is it to put in a block guard cause soon ill be pulling out my old pistons in favor of some pr3s and would like to put one in.do you have to pull the motor out of the car,,
