100 cfm more with anular and downleg boosters can't beat AFR

+ rhoads vmax lifters added long before the headers.
I'll have to see what the cam card says for install. Although I was there and helped on a little bit, I don't have the install notes.
What has bit me twice now is not having important build details like this and actual cc info. I will never do an engine again without cc'ing the heads.

I actually did really no retuning to speak of. When I go the car back with the headers I pretty much just used it. I had an opportunity before work really cranked up to get some datalogs, but then the LM1 flaked out (turned out to be the 9V battery connection). So that was that. it ran pretty well. I did try one step hotter spark plugs late in the year.
