Well as most of you know im planning an exploder engine swap
with a steeda #19 cam and bbk unequal lenghth headers wich i have already ordered. Now im debating on the roller rockers i want to put 1.7 but im wondering will the piston to valve clearance be ok
i dont have the specs for lift and duration on this cam and also with 1.7 rollers will the stock springs handle it. The motor has 68k on it and its a 00 exploder i dont want totake the heads off.

i found out that the cobras also cam with 1.7's so i guess it should be ok, im just nervous and i want everything to go smooth the first time.
What do you guys think about scorpion brand roller rockers?

cobra has better springs.. upgrade them or float

Stock springs = stock cam
Aftermarket cam (any) with 1.6 or 1.7 rockers = upgraded springs required ...

You need a kit with valve retainers (exhaust springs seat lower than the intake).....+ you would need to fit the heads with nylon valve seals (inner spring ID) with those springs......here are some options you could check....
1. TFS upgrade kit
2. FMS-M-6514-B50 retainers + FMS-M-6513-A50 valve springs

Just in case you were wondering;

Steeda #19 w/ 1.6 = .480 lift
Steeda #19 w/ 1.7 = .510 lift
