I'm in the process(as money allows),of putting together the parts for the edelbrock perf. rpm combo for the 400 in my'78 T/A.It will be a long time before I can afford aluminum heads.I have the 6x heads,but I've come across some #16 heads 2:11,1:77,72cc,I can afford.My questions are; what octane of gas will I need to run with the #16's,would I be better off spending the money on shaving the 6x heads to a desired comp. ratio?Also, do I need to have an adj. valvetrain with the perf. rpm camshaft and what's the best way to go about that.I'm finally out of questions for today(I hear the sighs)LOL.I'd also like to thank you all for contributing to the love of Pontiacs that I also have felt for a long time,even though I'm a new guy here.Thanks Al
