Performance Valve Springs Qld

[bigcarl]

im looking at upgrading my stock rb25 valve springs for new and heavier items fron allen at performace springs in queensland. my question is has anyone on these forums bought and used these springs on there rb25?? im running hydraulic lifters and step 1 tomei poncams 252degrees inlet 8.5mm lift inlet and exhaust. i recently bolted on a gt3040 600hp turbo , had the car pull 305rwkws on the dyno without a full remap. the cars power kept going until at 7000rpm with 21psi the valves began to float or something and one of my lifters at the rear stuck. im either going to go with these for $300 or tomei springs for $450 delivered from nengun. but ive ordered stuff from nengun before and it usually takes about 3 weeks. cars already been of the road for 2 to 3 weeks. your feed back would be much appreciated, thanxz carl.
