My heads are loaded, but I'm going to need to measure PtoV so I'll be taking off at least one intake and one exhaust. What spring compressor should I get just to use for setup?

I suppose I'll be changing springs in a few years, but it's is a very low mileage non daily car.

 

Its a bigger investment up front, but for later changes there is no comparison to the Crane/VHP spring compressor. Especially for an f-body where access to the back springs is a bear. It does two at a time and you can set it up on the head with minimum effort. Vinci High Performance has them. This is one of the better tools I have in my tool box.

 

Yep, what he said. Hands down the best tool on the planet for the job. You will find homemade spring tools for 1/3 the money as well but its something you can make yourself for less than $15 and its as primitive as it gets but it does work. Its a personal choice issue. Some people like real and nice tools, some people dont. Also what is your time worth? I'll do a spring swap in less than half the time someone with a homemade version will do it in. Also other versions put stress on the rocker bolt holes and threads that the Crane doesnt.

 

I would use the crane tool or the MORE tool you can get both from thunder racing.
