Currently I am running a set of 289 heads. I do not know if they are hi-po are not, but the seller said they were. I also have a set of 302 heads that were ported and polished, but I dont know what size they were worked too. Finally, I have a set of stock 302 heads with the rockers mounted on a rail with low miles.
Out of these three, which ones would be the best for me to use?
