That was using a Fel-Pro 8553PT gasket. Which is like 4.17. But even if it is bigger than the bore, wouldn't the benefits of the extra CFM still warrant unshrounding it? The stock bore is 4.04, mine is +.030, so I've got 4.07, meaning .1 bigger, .05 on either side of the circle. .05 isn't...
So, if you wanted to have a better valve job done on these heads, would the machine shop have to put in all new valve seats, or could you cut a 3 or 5 angle valve job using the existing seats and then also re-use the existing valves?
I called last week, and the guy on the phone said that they had like 3,000 orders over the weekend, so they were going to be a week catching up. I still haven't gotten a tracking number either, but I didn't pull the trigger until the 2nd.
