where do i find headers for my buick 70 model 455

@19urbabiiboii70 Is it a Skylark body? If so, you can get standard length headers from TA Performance in AZ. They also have shorty models that may fit other body styles too.

Did you do any other mods other than the cam for the comp ratio, or did you just install the cam?

The heads are converted iron Stage 1's. They were port matched to the older style TA SP1 intake with raised ports. I added roller rockers from TA. It was bored .030" over and is using some older Sealed Power pistons with valve notches cut. The rods were prepped/polished and are running ARP hardware. It has a Romac balancer from TA also. There's still a long ways to go before it's track ready.

Steve, thanks to you I bought this cam @ 2 months ago!!! YOU-THE-MAN!!!

D&S Performance is doing my '73 Buick 455. I get it next WEEK.

I have the TA long-style headers with 3" true duals ending with Thrush mufflers.

I can't WAIT to hear my motor!!!

It worked out to 8.62:1, but I called and talked to Dave before I chose the cam a few years ago. It doesn't have power brakes. I think it was pulling around 12" of vacuum, but the carb and ignition need more tuning.
