# 6 spark plug access hole Big Block

GTX JOHN said
I have several Big Block A Bodies with different brand
of headers (Currently TTI/Pro Parts/Hooker/Hedman) and I have never
had to cut any Holes anywhere to change plugs or have to lift engine.
Worst case has been box wrench on end of socket on #6 on TTI's.

Im attempting to run the B body Hedmans. I have it from several trusted sources that a #6 access hole is advisable to ease plug changes. In any case it’s done now.
