bah. **** this.

i have provided a direct link to my website on how to do the swap, parts needed, etc.

i have done the swap. this is more than can be said about everyone else who has posted thus far.

i'm not going argue with anyone who hasnt ever taken apart their motor or an H23 for that matter... a ricer never listens to those who know.

but, for those who actually give a shit and want real answers and not speculation:

1. H23 blocks are stamped P13
2. H23 internals are stamped P14 to designate the different internals.
3. H23's have FRM. i dont care about no stinkin manual, cuz if you read it word for word, you'll know the H series uses FRM... the F series does not.
4. I have successfully done this swap, and saw the FRM liner (even had to hone it for the new pistons)
