They are ported an polished asking 400.00 for heads. The cam has less than 150 miles on it never raced are Dyno pull with it was brought brand new, asking 75.00 The pro comp rollers was installed on my motor they were also brought brand new asking 150.00. I got a great deal on a ford race short blk 347 I went with a custom grid cam and some AFR 185 heads due to the pistion on the short blk were going to run into some clearence issue's thats why Iam selling this stuff I was intending to put on my 306. My brother knew a guy who knew a guy that was taking a small blk out a 92 Gt and going with a big blk so I made an offer to him, and the rest is history.
