Have a 69 GTO convertible with PHS documentation. VIN is stamped in block and tranny. Car has 48 heads (RAM AIR III?}, but not RA exhaust manifolds. PHS documentation makes no indication of other than stock engine. Any ideas why RA heads?

I have had a '69 RA III auto that was #'s matching and had the 48 heads. I have read a couple of magazine articles that backs this up also. So the mystery of what and why continues. The difference between a ram air 48 head and the non RA head are the springs.

Todd was mostly correct.
1969 #48 heads were used on: 4 speed GTO with or without ramair, auto GTO with ramair, 4 speed firebird 400 with ramair, 4 speed Gran Prix with high horse motor only 1969 #62 heads were used on: auto GTO without ramair, auto or 4 speed 400 bird without ramair, auto firebird 400 with ramair, all auto Gran Prix, Gran Prix 4 speed low horse (I do have one of these for sale with matching number motor) |
