Realnissan custom racehead package KA24E - $575.00 ( includes a set of custom comp springs, mild port/polish, custom solid adjustable rockers, custom upgraded valve caps & mild valve job, cleaning and reassembling of head)...... For 1200 plus shipping does this seem like a good price?

are going to go turbo or keep it na? sounds like a good price to me but im no expert, just make sure the comp ratio is where it should be for your desired application, be it n/a or turbo. good luck

Wow. 1200 shipped is a good price, but I really think that turbo + nitrous + 9.5:1 compression is a bad thing, unless it's very tuned. And if you had the cash to pay for that ammount of tuning, you probably wouldn't be asking if the price is right. Loose the 9.5:1 compression for that. Also.. this is very dependant on how much boost you plan on running, if this car is drag only or daily driver, and what turbo.
If it's a daily driver... I would forgo head porting. Look at every last high powered KA motor. Every one of them has had a ported head at one point or another, and every one of them has overheated and warped/cracked heads. Finally... if you need a couple cars to look at, they are at Chris May's Mod List (Read the engine description. Stock ports.) and also, dubbed the "Fastest 240sx in the World" with 600+hp (on nitrous) with a stock ports. Valvework is awesome, but not porting and polishing. But.. others may disagree. -Jeff

Im not trying to sound like a smart ass but im SOHC, so i have lower compression 8:5:1 i think.
So ported polished heads tend to over heat and crack easier? sean

Just get the heads polished to smooth out the ports....
If I am right about that 240(Chris May's) I am pretty shure that he has blown that motor(if its still the orig) three times. I don't know if it is the same car though....
