Ok, I am in the middle of my 1350BB build. I have got megacycle 480/455 cams, and a falicon 1/4 stroke crank. I also bought a 1250 kit on ebay. I powder coated the SE heads black and put in over sized valves on the intake and exhaust and had the seats ground. I did not have any other work done the the heads. I have been told by several people that you can not port and polish the CNC SE heads any more because there isn't any room to to take anymore meat out. But, I was told that you can hand polish the exhaust ports and make the heads flow alittle better. My question is has anyone had any experience with this? Enough to say one way or another weather it would be worth getting done? And, if it was worth it can anyone recommend a good place to do it? I live in Va.

Thanks for the assistance
Brian

Yeah he can, but I am trying to figure out if it is worth it to have the intake ports polished.

If you want to see if polishing makes any difference you can do an A-B ( before and after) test on one of your stock heads without experimenting on your good ones. You always practice and experiment on a head you don't care about.

Im with Dale on this, me and him were talking about flowing heads just yesterday.

I guess if the point of the exercise is to make flow bench numbers, go ahead. I think most of us would rather have better time slips or dyno numbers than flow bench numbers. This has been done so many times I wonder why it just comes back over and over.:soapbox:

If you have a problem with the thread dont read it. Or respond. What do you have to bring to the thread anyway. Time for you to step down.:soapbox:

.480/,465 cams... I thought they were .480in/.450ex. What valves and springs are you running?

I don't have any problem with the thread. What I have to bring to the thread is what I wrote, do you have a problem with it? You don't think there is any value or truth in it? If you are threatened by what I said, perhaps you should look to what issue you have with it because there is nothing wrong with what I wrote.
So is this where you are in charge of checking credentials to post in threads again?
Time for you to take a prozac and ignore what I wrote or respond on the substance of it. :kiss:
