I'd like to see another cut. Could you basically cut the bottom 1/3 off of the siamesed exhaust section. You could just cut the Cam side half you got after the 4th cut. There are 2 small freeze plugs on the cam side of head. I'd like the cut to go through those holes, parallel to the surface of the exhaust flange. I will try to get a picture with a line drawn on it, but I have never been able to get pics to upload. I always get a database error.
Cool Its about time someone wanted me to cut something.
First can I ask why you want me to make this cut? This is what I think you are saying that you want me to cut. Did you mean the yellow lines, left, right or both, or did you mean directly through both plugs along the green line. Let me know where you want it and I will try to post it tonight if I can get the cut off today.
You can upload pics when you update a thread but the pics have to be less then 50k. If you load a pic to your account in the photo upload option and then copy and paste it to the thread there is no maximum size photo and you almost never get an error.
Your idea of measuring runner volume has merit, but flow is more important. Maybe you can find an affordable place to flowbench your heads before, during, and after porting.
Yea, I know, The main reason I did the test with the rubber was to figure out the amount of material I removed and be able to compare the before and after. My machinist said that he would flow my heads for $50, I think he ment $50 for the preport but I asked him if that was for pre and post and he kinda went along with it and said that he would do both for $50. Not a bad price to find out the flow, consider that I dont think anyone on the forum has done this to their heads. I have to agree, If I dont get the flow test done that would leave this threat incomplete. Thanks for the pep-talk and good smacking around.
Oh I just got my carbide burrs to start the port job. I will first port the last section of this head that hasn't been cut and then disect it to verify that I didn't remove to much material and weaken the integrity of the head.
TO BE CONTINUED...
