B18a1 block with a B18b head...(HELP!!)
I made a post earlier about bending my valves, but now I need tech advice to get my hatch back on the road.
It's a b18a1 black from '90 and I found a replacement head from a b18b (94+). So basically I'm just doing a head swap and keeping the b18a intake/exhaust mani, dizzy, etc.).
If someone could please let me know the details (a quick how-to, what gaskets to replace, what I'll need, etc.) that would be awesome. This is my only car, so I need to get it back on the road asap. Thanks....

Should be just like replacing a head. You'll need a head gasket, intake manifold gasket (if the B18a IM fits the B18b head, I'm not honestly sure), and exhaust manifold gasket. Wouldnt hurt to replace the spark plug tube seals and valve cover gasket. Also keep a tube of Honda Ultra Flange Sealant nearby for the valve cover gasket. Should be straight forward as long as it all fits together.

Everything fits... no big deal.. everything bolts up... did this a few months ago on a 1990 integra GS that broke a timing belt. We had a '98 LS head laying around and slapped it on.
Don't you have a Hayne's manual or something? They help with this kind of ****.

I figured it'd be just like replacing a normal head, but I'm not entirely sure how to do that because I suck at fixing things...

I do have a haynes manual but I'm wondering if they are just making it waaay harder than it seems. You guys make it seem much easier than when I crack open the manual...

The haynes manuals are junk. The best manuals available are the helms manuals (Honda Factory Service Manuals). They can be bought from http://www.helminc.com
Head swap should be fairly easy. Remove the intake manifold bracket from below, also remove the 3 intake manifold nuts from below. If there is PCV lines, remove them as well. Go back to the top and remove the rest of the intake manifold nuts and then slide the intake manifold back to clear the studs. Remove the exhaust manifold nuts and pull the exhaust manifold forward to clear the studs. Undo the wires on the right side (distributor, ECT, and anything else). Pull the valve cover off, remove the timing cover. Loosen the timing belt tensioner and slide the belt off the cam gears. Remove the bolts that hold the inner timing cover to the head. Now remove the cams, then remove the head bolts. Lift old head out, set new head in and reinstall in reverse order.
Pretty simple job. The hardest part is getting to the lower intake manifold nuts.
