Bling head

Hot rod bling head

I...I just can't help myself! While the top end is off, I gutted the head and fired up the die grinder. Ported the seat to bowl transitions, ground the guide bosses down a bit, and hand sanded with 150 grit. May take a stone to them before reassembly just for fun.
Deburred, sanded and polished the chamber, too. Do all of these heads have the crappy deck surface like this one has (the giant half moon "low" spot at the top of the pic, in the quench area). It wasn't corroded, it was cast this way:

Zippity frickin' doo dah! :loco:
Anybody ever try this? Worth any gains on a stock engine?

my head is ported. thats where these motors need all the help they can get, cause of the 2 valves. you should notice big gains

Did you recontour/enlarge the ports or just knock the guide bosses down?

Heck yah dude, you should see good gains. Ive nevere seen a cast that dented before. We'll never seen a head that clean before either. Hope you valve seat are good now though. Do an over-valve on the intake by chance?
