Is there a BIG weight difference between sealed power and stainless steel? Also will the SP be safe with my combo? The heads are level 3 ported, TA 1125 dual springs on a short block with 10.5:1 comp. and a decent cam (.530/.550). The highest it will ever spin is 6200 RPM, but I could limit it to 5900 if it makes a difference. I have a new set of SP that have been back-cut, is it worth it to spend the money on SS and shelf the SP? Thanks, Steve Walsh
i think the ss valves just handle the heat better. i think your exhaut valves are stainless allready.
