RE: Check the head exhaust surface
By Courtney Bolze - 10/22/2002 11:45:41 PM; IP 207.68.52.38
I installed FPA tri-y headders on my 69 mach1 390. I r& r the engine, installed heli coils in the exhaust bolt holes, made sure the headders and gaskets fit while on the engine stand (finger tips threading all the way in). I put lab metal on the head exhaust surface and milled it down with a file to get the surface where it would not leak (did'nt want to have the heads surfaced). For installation I had 2 bolts holding the C6 on, no motor mounts at all, engine hoist holding up the engine as high as it would go, trans mount loose and they went on easy. Next time I will remove the entire steeering linkage (tie rod to tie rod, pitman & idler arm, and ram to give me more room to reach up etc.) Still had to shim the mounts about 1/4 inch to keep off the shock towers. Finished the system with 2 1/2" H pipe, hooker maximum flow mufflers and flowmaster mandrel bent tail pipes. It's very quiet to about 80 mph and SHAKE the tiles off the tunnel walls at WFO :-) Going on 2.5 years now with no leaks. Hope this help, just check the heads for pits/flame cut gouges because it will leak if it has them. CNB.
