Break in problem...

put a healthy fan in front of rad. front end jacked up. thermostat OUT. make a mark on dampener 2&7/32" CW from the TDC slit & have your dist man set it to that (vac adv capped) when it fires. read "breakin secrets" at www.mototuneusa.com goose the throttle many times. they're glowing from either way too lean (like an acet torch) or too rich (fuel still burning in the manifolds)
