RE: Buying the AFR 165's 3 quick questions
I'm not for sure, but I've always been told that if the duration is under 230 then clearance isn't as big of a factor. The stage 1 is 221/225, so if the above is true, it wouldn't be a problem....but, like I said, that's what I've been told, so take it for what it's worth.

RE: Buying the AFR 165's 3 quick questions
i plan on upgrading the springs when i get the AFR heads, but i wanted to use a cam like the TFS stage 1 w/ my 1.7 rockers but that puts the lift on the exhaust valve up to about .548, so I dont know if I should even try it. My friend is running .535 no problem...
