Ok, so last week I noticed my valves started tapping on my b20b. I thought that i'd be able to just adjust them but then i was googling around today at work and I found some info about b20 heads needing to be replaced because of valve seats wearing out. From what i read it seems some late 90's b20b's were known to need head replacements because of this problem . I've never heard of this. So just incase i need a new head I'm debating on which head to get. I would go vtec if i can find one at a decent price but I doubt that so I might just get an LS head. Then i started thinkin about b18a's and I was just wondering what would be the pros/cons of such a combination? A b20b block with a b18a head. as far as i know, all b-series blocks and heads should be interchangeable except for the early preludes b20a right? would this be a dumb idea, would i notice any big loses in performance? My engine is basically stock. I have a maglaflow cat, dnx mid pipe and flowmaster rear section. Thats about it except for a cheap autozone "racing"air filter. What would I use to do this, which head gasket, timing belt ? This is just an idea because there's lots of DA's in the junk yards around were i live so getting a DA head is real easy.

I couldn't say with 100% confidence, but I believe I had read on here that the CRV B20 head and LS B18 head are the same thing.

Yeah I heard that too but thats not the head i mean. i'm talking about a DA 90-93 integra head. aren't those b18a's ? I though LS's are b18b's

the b20 head has little bigger ports... (p8r head)
your better off going with another b20 head.

If i were in your situation, I would keep the short block and get a b16 vtec head for $350 complete.

youmayneverknow

i have seen STOCK crv b20's drop valves....

It doesn't matter if its a LS/RS/GS the motors are the same except for the sensors and such for OBD.

the gsr vtec on the other hand is different

i have a reman b18a PR4 head... make offer
