Looks like they did a better job of the port entrance/exit than they did with the BB head.
I am a little puzzled why they cost $320 more than the BB heads though.
If you open the exhaust exit, won't it be out beyond the size of most headers?
The exhaust port kinda has a Herman Munster forehead on the exhaust short-side and needs widened some and shaping. Like I said on these its all free checking for a Friend to get him up and running so the grinder won't be touching these. It will be a good test. On my car I will make the exit however I deem necessary because my headers (1 7/8 hedmen) have already been modified. The headers on my Duster are W2 headers with adaptors.
