I have a set of those in my garage, they all came with small 1.7" intake valves.Can anyone explain these...there on my 327 that was out of a 68 camaro...This is the first I've seen these kind of hump...Any clue's..???
wow, 12.60 in a chevelle? what was the engine combo? like compression, cam specs, engine size? what year was the chevelle?i have a set of 492 angle plug heads i got given to me. yes i spent some money on them but they are a rare and very sout after head. this is gms first version of there bowtie head. my chevelle ran 12.60 on motor with these heads bone stock without any port work. changed them out for a set of edel. rpm heads and ran the same time. a good deal and a street motor they are a grat head IMO. i also have a set of 186's that are in excelent shape if anyone is interested.
These heads in the past were the deal!are these still good heads to run ?.........i mean there are lots of companies out there now that sell good or even better heads right? and by the way....looking at casting numbers which sets are better than others?
