Tri-Y Headers for an IMCA

[fleming10]

What would be the best set to buy for a chevy small block (between shoenfield, beyea, dynatech)? Has anyone used or had good success with them?

[GUARDRAIL]

I don't think you can use Tri-Y headers in IMCA

[TALON75]

All primary header tubes must enter directly into one collector at same point at end of header

From IMCA rule book.
