hi guys

i found a good deal for a b18c5 short block and i was wondering if i could just bolt on a b16 head to it w/o any mods, ie. valve springs, retainers, etc.
if i just bolted on the b16 head would it run safe ?

just curious b/c i'm looking to swap my motor, but if this is an ok idea, i may just swap the short block and keep my head
this is for a em1 btw.

any info is appreciated, thanks.

 

yes, you could its the same head just the internals change the type r head are stronger

 

Yes. they are both PR3 heads so basically the B16 head itself and ITR head is the exact same.

 

exact same casting but yeah basically the same but itr is ported a tiny bit.

 

CR won't change either so you won't lose any power - at least I don't think it will.

Might be a little weaker (or not to the best of its ability) at top end b/c I don't think the B16 springs/retainers can last to the RPM that the ITR head can w/o floating the valves. So I'd use the redline of the B16.

I could be wrong though - just a thought.

 

The b16 head will produce less power than an ITR head thats for sure. You could just upgrade the internals of the head later on when you get a chance.
