I have a 331 sbc and my track has a no porting rule and 23 degree steel heads and flat tappet cams only so looking for the best head out there.would a 200cc dart platinum or the pro action head be a good choice.by the way this track is really small but banked alot.
14* RHS is the best iron head, but do you need it?
The real question is....how do you get her to do that while ironing?
lol, the real question is how do you get her to do that period?
if your allowed to port and polish, does it matter as long as its a quality head? lol
You can't make 800+ hp with a dart 23* no matter how much you port it if thats what your asking. He has a NO porting rule as stated in the original post.
i dont think your going to make 800 with any unported iron head on a 331
I'm a farmer and combine head is among my favorite....!
And then boat head.....
The worst I ever had was wonderful..........
And that was 1 loooonnnnnggg day....!
us trashy truckers like a polished head,..seems to blow better,..an seems you can turn her up more before she quits pull'in on the top end....just say'in...lol
You crack me up Tom, I miss the old starving racers days, shame that deal didn't work out.
Are you allowed to angle mill your head? What type of pistons must you run? I have run at a track the specified 23 degree heads and flat tops. We would run the Platinum head 49 CC chambers with 200 CC runners and then angle mill them to get the compression up.
we have to run 23 degree and can angle mill,how much did you mill off yours and what pistons did you use?Quote:
