Found this list of nonos that i wrote up a couple months ago.
Bought these straight from the dealer, and the results were no good.
Valve springs are the same seat pressure as stock, but 20lbs more at open.
Coild bind is too soon.
Cam takes spring up too close to the coil bind.
Coil bind needs to be .950" or less.
Seat pressure should be approximately 75-85lbs, while seat pressure should be approximately 175/186 at valve fully open.
Finally coil bind should be at least .100" from full open.
Conclusion
Ended up putting some crower springs in my stroker. and wasted a little mountain of bills on hks' proven performance.
Results taken from my engine guy here in canada at Mississauga Engines makers of Canada's fastest import and a whole lotta american muscle.
