yo yo,
i was wanting to know how important is it
to upgrade the valvetrain when boosting an h23,
i plan on getting the block completely built up,
but i've heard that the stock h23 head does pretty good.
what are your guys thoughts on this aspect
thanx,
chris

 

how high u plan on taking the rpm?
balance the rotating assembly (crank, rods....).. thats for damn sure

about 6600-6700 rpm's
not too high,
the block will be completely built up

 

If you're gonna get serious w/ the head, ya gotta balance out the bottom end. SO......only try it if you got the motor already tore apart, and you have the money to spend and time to kill.

I've seen too many high-HP H23's w/ stock head components, I wouldn't screw w/ it.

But I know Crower HAS come out w/ a cheap set of cams and springs/retainers! Might be worth lookin into.

 

hmmm. i've never heard of crower having anything for
the h23 valvetrain the block is going to be most likely
benson sleeved, crower rods, cp pistions (swain-tech coated
and everything blueprinted and balanced, so i'm not worried about the block.
This is why this qeustion comes into hand. If building the valvetrain isn't
that beneficial, then i don't want to bother with it at this moment in time,
but my first step is building up the block

 

unless your running high lift cams i would keep it stock for that rpm.. thats nothing

 

sweet, that's what i wanted to here
