Need a little help from the experts on ported heads.
I found a brand new pair of DC heads that have supposedly been ported by Roush/Yates.
My question is in regards to the combustion chamber work. Should they be smoothed and polished to get rid of the cut marks or grooves where the cutting bit has ran to get rid of the stair step affect or do these look like they are good to go as is? Nothing has really been polished on them but my biggest concern is if the cuts/grooves in the combustion chamber will cause hotspots and pre-ignition or if all looks good to go as is.
Also if anything else stands out as a red flag please say so!
Thanks
Ken
