Thinking ahead about headers, clearance, spark plugs and all that fun stuff specifically related to C3 Corvettes. Looking for feedback from those who have gone through this before.
So here’s the setup.
1978 Corvette
Gen1 350/(383)
Dart SHP 200cc aluminum heads
Straight plugs
Manual Trans
Power steering
no AC
no emissions
Looking at Hedman 68306 headers. Need to call Hedman and ask about the “Will not fit with steering damper inside front crossmember” and to get their recommendations.
Install question:
- Install the headers on the engine while on the stand then install with the engine.
- Drop the headers in the engine bay before putting in the motor. Tie them out of the way and then install after motor is in.
- Install the engine without the headers then install the passenger side header from the top and drivers side from the bottom.
Spark plug questions:
- Are shorty plugs a requirement with these headers or will I have to wait and see after I get it all assembled?
- Does a gasket seal, 14mm, .750 reach shorty plug exist other than the Accel 0414S
