Ported 6x-4 heads
I have a set of 6x-4 heads with a mid port job for sale. Heads are currently set up for a solid mechanical camshaft. I was hoping to run these on my 455 stock motor but I am going to build up my 69 WT 400 instead. Bought these 4-5 years ago and they have been kept on a shelf in a dry shop since then.
SI valves 2.11 and 1.77. Installed height of 1.6 inches. They flow 255@ .550 lift and 215 on exhaust. I was told that the low lift flow was really good as well. I am the second owner of these heads and I have not used them since I bought them over 5 or so years. No flow sheet, purchased from a board member, but heads were done by Mr. P-Body. The cam he ran was a Ultradyne solid lifter. 243/251 duration @ .050. The lift was 518/530. $600 or best offer. |

more pics
These came off a 12.7 second 461 stroker motor. Untouched since taken off. It looks like the intake runner is wet and oily - that is from the cleaning spray from the adjacent intake when I was cleaning it out. They are not oily or wet - just a little black carbon.
