Is there any difference on the 5SFE heads from 1990-1999 other than the valve covers?

are you talking about differences in the whole engine or just the heads. Only difference I know of is some Camrys came with stronger internals than the celicas, I think.

Just the head. The reason I want to know is because I need to replace the head in my 93 gts. I need to know what if anything extra I will need by getting a 90-91 head, or a 94-99 head. It is my only means of transportation other than the bus system which sucks. So I need to get this thing up and running as soon as possible. The reason I need to change my head is because who ever owned it before me overtightened the #2 spark plug and messed up the threads. I was able to drive around on that for about 3 months but the other day it shot up out of the motor, and hit my hood. The spark plug wire was still attached but it had been blown out. I had my tools in the back, but when I went to try to screw the plug back in it would not hold. It just spun around freely. When the motor had gotten cold, I tried screwing it back in and it held but I could feel that it was not really firm. I tried turning on the motor and it shot right out. So needless to say I want/need to replace the head.

I believe the PCV is placed differently on the 90 - 93 then a 94 and up 5sfe head!!

I would like to know the profiles on the 98 camry cams, are they more aggressive?? if so than this could be a upgrade for our older 5sfe's!!

Problem is I only vaguely remember so can't offer any hard facts on the 98 camry (if that is in fact which they are), but I was thinking the cams moved the peak power up in the RPM band, to around 5700 or so instead of 5200.

At least you made yourself a nice projectile weapon there.

T Spoon Im pretty sure your right because I saw a dyno of a 98 camry 5sfe stock that made power higher into the rpms then the older 5sfes. And I remeber Hooligan telling me that camrys also came with forged/ stronger internals(rods and pistons).

i believe the cam profile on the camry is .319 lift and 200 degree duration @ .050 on both intake and exhaust. also, a more narrow water jacket on the head.

Head ports are smaller on the 92^.
Valves are different for this reason.

I don't know about cam profiles.

But I doubt the internals are much [if any] stronger.
Even older 5SFEs are forged. Forging isn't that big of a deal anymore....
It's common on stock engine parts, and has been for a while.

PCV is on the valve cover, not the head.

I would suggest you source a 92^ head. This will work better with your ECU.
But a 90/91 should work ok. I doubt there will be much difference.
