Valve spring help.

Don't put a double spring on that cam. It isn't needed. Too many people put springs that are too strong and all it does is waste horsepower. Crane sells a single w/ dampner that's around $70. Comp sells a single w/dampner for around $85. Don't plan on reusing the old retainers and locks. Those will set you back another $60-$70. Ideally you should get them installed so the seat pressures can be set. There's some more cash. The aerohead $500 specials are sounding pretty good around now, aren't they? good luck.

I got to agree with dusterdon. I'm running ported 902 (that's right 902) heads on my 383 with the .509" MP cam and this engine runs hard to 6000RPM. The springs I used are the Crane singles with dampeners and have had no valve floatation problems mind you I haven't taken it :burnout: past 6000 and don't intend to.
