    the Buick heads

     



    First of all, another lesson on assuming what the seller sez is correct. I was told my nailhead was a 401, but the bore size proves it to be a 425!!! Guess it was my turn to get a lucky break on trading parts!!!

    I build hot rods, and thus do not consider myself to be an engine specialist. I have put a lot of them together but I've never done a nailhead. I would like to do a bit of match porting on the heads, I do not plan on a flow bench type job, just a bit of a touch up on the runners and maybe some bowl work. The heads are being redone for 1.94 intakes, and 1.60 exhausts, stainless, of course. The induction side will be a 6 deuce intake. How's about Tech, Denny and some of you other engine guru's helping out with some suggestions??? Thanks

    The intake runners seem to be a decent size. The way the nailhead is built dictates that the are a bit long, but there is a nice straight shot from the intake manifold to the valve. As pictured, the plug is more or less centered in the head, the motor was stock with 10.25 compression, and I plan on using Speed Pro or Ross pistons on the rebuild. What do you think, guys???
