crxfreak is right you will get more power but it requires alot of work one the b16 head is better and requires modification to bolt on also since the b16 head loves to rev you may want to secure the block since its not made to rev as hard and you don't run into problems in the long run. also with that engine i would consider going turbo

One thing I will agree on is do work to keep the motor lasting, a set of ARP rod bolts are a must.

lsvtec is covered here quite often search.

If your asking a question like this you should do a little more research

https://honda-tech.com/zerosearch not being a d*** just saying you should research what your getting into before doing it

Umm what?

Both B16 2nd gen heads and ITR heads are identical in cast. ITR head has a mild port and polish out of factory. GSR heads simply have different bolt patterns for the intake manifold but other then that it's all interchangeable.

First gen B16 heads have single valve springs and aren't as rev friendly out of the box, but both B16 and B18 heads rev pretty much the same.

The best revving head, stock, is the B16B, but it's cost is simply not worth it.

For an lsvtec, you MUST do rod bolt if you plan on revving higher then 8000rpm. I've seen lsvtec blow up after a few weeks of 8500rpm. The bottom end is not designed to rev, so special concideration must be taken. It will also be a low compression engine, don't expect to lay down more then 160whp.

Google pics or look here, it's more then just a few bolts.

While parts do interchange there are things in the head it self like it's shaping that differ them.

Is that a fact? I'd like to see what other differences. There aren't any noticeable difference that would make the GSR head a bad head to use in an LSVTEC tho.

Ah, the neverending battle between the P72 and PR3 head casting. Who knows which really IS better. Given that there is no definitive answer yet after all these years, I am inclined to think it is a draw. Regardless, either should work fine on an LS-VTEC, and the B18C1 head will give you a better compression ratio if you decide to use the stock pistons.

I want to see some flow charts between the pr3 head and p72 heads. That's really the only way to know for sure, anything else is speculation really. But it is a fact that the p72 head raises compression in setups like this. I know someone has a link or something where a comparison like this has been done
