I quit doing outside work. Several years ago I had 6-7 jobs lined up telling local friends to drop heads off in late October early November. Zero upfront money needed or wanted unless they were changing valves or springs. That kept me moving on my end. Nothing and I mean nothing started showing up till January. I race from March into November so my stuff needed work to so I quit taking work. I never charged over 800.00 except for one job and that included porting the heads and two ported and flowed intake manifolds so I wasn’t getting rich on the deal.
