Yes, as long as you swap upper timing chain covers as well (keeping the 92 front cover with the 92 head). Only 1 bolt will not line up, and it isn't important.

what's the upper timing chain covers, and is there a performance difference between the 2 types of heads. Is the swap hard to do? If possible pics would be nice...Thanks Jeff in advance

ok...so I did some more rereacrch about the compatibility of the s13 and the s14 head. This is some of the stuff that I found:

"To answer the question, there ARE differences. The 91-94 head is milled for a different valve cover, with different size threads and placement of the bolts. Another critical difference is the 91-94 heads do not have the bolt hole tapped behind the upper timing cover where the distributor meets up in the same place as the 95-98, so using a an earlier head will cause an oil leak if that's not sealed. Sunbelt Motors showed me that trick. "

Ace- I know you did the head swap before, I was wondering if you had any problems with this or anything thing else during the swap, could you feel a difference in performance???

Couldn't tell a difference in performance because of the head since I had ported/ polished it before installing it (thus it wasn't really a stock S13 head).
The bolt hole behind the distributor doesn't really matter. Didn't leak for me, at least. Like I said, only 1 bolt didn't line up, and it wasn't a very important bolt.

The upper timing chain cover is the front cover. It's what the distributor mounts up to.

what kind of head gasket did you use...s13 or s14?

*AceInHole* · 04-20-2003, 09:06 PM

OEM headgasket is probably the best thing out at the moment. Takes about a month or so to get it, though.
