I just bought my first jeep, 85 CJ7. I am tearing down the engine to reseal, re-ring, re-cam, and replace the head. I called my local machine shops and for them to re-do the head (clean, new guides, valves, seal, etc) would cost me $300-$500. I did some searching and found this site.
I can get basically any head I want for about $186. I have also read about 4.0 head swaps increasing hp. If I go this route, I know I have to get a 4.0 Exhaust, but what other things will I have to get? What year 4.0 is best for the swap?
I don't have a lot of money so I want to keep this as cheap as possible, but if I am replacing the head anyway, would it be worth the time and money?
As far as intake, i plan on keeping it carbed but upping the cfm. should I go 500cfm or keep it lower around 390?
thanks in advance.
