Head Help!

[Barefoot]

how about this u post a pix of the head. if it has pr4 on it its a ls head.

i know its a ls head, but this goes in hand with that problem you were trying to help me on. If its a b18a head, and i have the b18b cams in there, i was reading the intake cam on the b has higher lift than the a, which may be why the cam cant rotate. but ill post pic. As you can see in pic on the right is stamp, but on the left, here is where my confusion really kicks in. I know that pre 92 or 93 the bolt pattern on the IM was different, and as you can see, that freaking thing says 89. So theroretically, my supercharger should not bolt up since its for 94 and up, but, sure enough, it does. So, WTF IS GOING ON!!!

The bolt pattern shouldn't be different between a b18a and b18b head

All of these quotes are off of honda tech:

Please search, this has been covered a million times. It's mainly head differences (cams, intake manifold bolt pattern, etc.), but some of the holes for the sensors may be different in the block (not that big of a deal but there are differences).

Also the b18b has bigger intake ports.

92+ heads has bigger cams and a bigger im.

that last point might be your problem. if the 92+ has bigger cams, maybe you have those cams installed in a 90 model head. one of those cams might be way too tall causing valves to touch the piston.

as far as the bolt pattern...perhaps there's no difference in the bolt pattern. maybe the guy gave you false info. i just did a quick ebay search for "B18 intake manifold" and i clicked on the first auction for a skunk2 intake and it clearly states:

Application:-
Any Car With B18A or B18B LS/RS MOTOR

which would lead me to believe that there is NO DIFFERENCE in the bolt pattern for the intake. there's a few auctions on there and they say "for 90-01 LS,RS,GS B18 a & b engines"

i also went directly to the skunk2 site and it's the same info:

yeah dude...so i think you might have the wrong cams in that head.

see this is what i thought. i was giving him benefit of the doubt. i figure if he is building a motor he couldnt fuck up something as simple as installing cams.

lol, hey sometimes it happens. when your mind is moving at 1000 miles a minute it's easy to make dumb mistakes. lol, it took me 2 days to figure it out when i made that mistake.
