aiight it's like this...i've got a 2000 honda accord (setup for road race/autoX), a 99 civic Si (setup the same as the accord), and a stock 95 acura integra LS 5 speed....i've been having the teg for a while now, i had big plans for it but i decided to scrap the project because i picked up the Si (which is now for sale) and im buying an EVO IX MR when they are released...anyway the timing belt snapped in the teg, bent 8 valves, i haven't gotten it fixed yet but the guy that's gonna do the fixing has a B20 head that he could put on my B18B block...would this produce anymore power than just replacing the valves in the stock head?

 

they share the same heads. the cams may be a little different but i wouldnt expect too much hp gain from it.

 

The cams are the same, if the head has PR4 stamped on it, it's an LS head and identical.

 

so the B20 engine and B18 engine have the same head? just different blocks? ahh aiight...thanks for the help

 

Most of the time, yes. There are some B20 heads stamped P8R that have a head with 84mm combustion chambers instead of the LS 81mm.
