I am thinking of replacing the factory head on the B18 in my 1996 integra with a GSR 72-1.
Is it a straight head replacement?
Are there any concerns with doing this?
I was told that there might be lubrication issues to deal with.
Any info would be appreciated.

Its called vtec conversion, please read the stickys at the top of the section.

I cannot find the V-TEC conversion sticky. Where would i find it?

It's in the all gen FAQ sticky

In the first post scroll down to LS/VTEC and there should be some useful links

This is the best LSVTEC write up I used it on a few vtec engines I built as well.

For a visual, Honda Street Garage on YouTube has a solid video on doing the conversion. He does a B20VTEC, but applies the same to LS block too.

Tks. After reading the sticky i have decided that this is not an option that i want to persue.

IMO you should look into a JDM high compression B20 long block! its a better replacement than the LS B18. Its a 2.0L so more torque! and will be a straight forward drop in but might need some parts from the LS engine to work better but everything swaps over perfect. Not mention they are dirt cheap like $550! look at Hmotors.com for a legit swap.

just make sure it IS a high comp b20, well worth.
