head hunter

--------------------------------------------------------------------------------

So, as I have stated before here I have a 318 with 340 J heads, it was this way when I bought the car, so I don't know what all may have been done to them, but I do understand the concept of port velocity somewhat, and I have the chance to buy some 302 heads from a san jose local that post's around these sites pretty often, and I can get a good stage one port job for 125 bucks, and I was considering buying the heads and having the work done, since my car is a street car, and I'd be able to raise compression and leave my tranny combo alone. I have an A999 with wide ratio gearset, and 2000-2200 stall factory cop car converter. The 220/228 solid I am buying would not be adversely effected I don't think, and with a quality port job I'd still have a decent top end, don't you think? My question is, those 302 heads are "swirl port" heads, right? They have the heart shaped combustion chambers, I think they are like 60 cc's, if I had them ported will that ruin them? The swill effect, I mean. Would I defeat my purposes to go through this when I could just run the J's and leave that alone? I'd be afraid to port the j's for fear that my small cubes couldn't use them. What do you guys thinkl?
