Hi Scott, I ran into the same problem with those springs, an APT (Kent?)
BK74 cam and 1.55 GT6 roller rockers (net 0.5022 valve lift). I kept
everything the same but used a 1.50 Spitfire roller rocker (net lift .486)
and bought some space. That set up is OK up to ~8K, broke an inner spring
when the engine revved to 8500 at the Glen after the flywheel bolts sheared=
.

Let me know what you come up with.

thanks
mike h

I bought my Isky dual spring set through Ted Schumacher to match his cam th=
at he also sold me. Works great. Talk to him about the details.

Try British Frame and Engine. =C2=A0They are not as stiff as the Isky Sprin=
gs, but can tolerate more lift. =C2=A0Be sure you have adequate seat pressu=
re as well as sufficient pressure at full lift, per your cam specs. =C2=A0T=
hese work well with the Tilden 298 cam from Ken Knight.
