found nice heads March 21, 2007, 12:25:20 PM i found heads that have 1.9 intake and 1.6 exhaust valves, will these work with stock pistons using the HO cam? Quote Selected

found nice heads Reply #3 – March 21, 2007, 02:24:21 PM they are from Arrow head technology i think, its something like that.um, i cant remember but how small of chambers can i get? Quote Selected
found nice heads Reply #4 – March 22, 2007, 09:29:35 AM Never heard of that company.....Got any info on them? I couldn't find anything.....The smallest chamber you can use on a flat-topped 302 AFAIK is the TFS heads..... Quote Selected

found nice heads Reply #6 – March 22, 2007, 12:41:09 PM Nope TFS heads are one of the few heads that work with the flat top pistons the SOs have. TurboCoupe50 uses those heads with a TFS stage 1 cam and flat tops with no problem. Quote Selected

found nice heads Reply #11 – March 24, 2007, 09:06:27 AM I think you should save the $400 and buy either gt-40p irons, or pick-up a set of used alum edelbrocks or tickflow heads. I bought my edelbrocks used for $700 shipped and they were straight from the machine shop ready to go.Also look what a 69cc cc is going to give you, under 8-1 compressionhttp://www.flatlanderracing.com/trwfordsb.html Quote Selected
found nice heads Reply #12 – March 24, 2007, 09:35:36 PM well, i have the SO motor so i cant have those kinds of heads... cant i get the chambers milled though? Quote Selected
found nice heads Reply #13 – March 25, 2007, 03:07:56 PM I think they'd be decent heads on a supercharged engine. Quote Selected

The bottom ones labelled "85-87 HO" are more accurate and still on the low side (those have valve reliefs if they are tru HO pistons).....69cc is a bigger chamber than stock and will lower CR. Stock HO CR is determined with a 64 cc chamber. Quote Selected
