Over heating problem! From head swap?? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I did a search and couldn't find anything about this, so here goes....

Did a head swap on my '95 240sx. I replaced it with a freshly rebuilt one. However, when I was bolting it back on the valve cover didn't fit. Therefore I got a head with a different casting number! So, I went and found a '91-'93 valve/timing chain cover and it seems to have bolted up fine! Now, my car overheats! I have a new t-stat, waterpump, timing chain. I am thinking that it could be the head gasket (although the fitment seemed good). What do you all think or is there something else I need to do.

BTW, the casting number on my stock head 70f and the new head is 53f.

Thanks for the input!
