I just have a quick question......I have a 69 302 where the heads work great....I pulled the engine running beautifully......How would those heads compare polished and ported to a set of GT40ps?

Also how would they compare both polished and ported? I figure both options would be better than the e7s on my car currently....just need a lil direction

gt-40ps will be better in this instance

oh ok.....I just thought that the 69 heads would have more material there for porting.....I was just wondering, cuz I know where I can get some gt40ps for 150-200 bucks, but I was thinking about the 69 heads cuz I already have them laying around


Thanks for the quick reply!

if they were c9oe heads and had the smaller cumbustion chambers they might be worth it but only if they had bigger valves already installed, I cam across such for 300.00 a set of 69oe heads with manley ss valves 1.94/1.50 and they were lightly ported and converted to stud mount rockers

heck the gt40ps have a 58cc chamber anyway. and are really a pretty good head as far as stock heads go they may be the best inline non canted valve head Ford made.

c9oe or d00e

Hands down GT40ps. You will have to put Hardened valve seats and do a partial port (blend the bowls) on those heads to get them to flow with a GT40p head. The GT40p has a more efficiant combustion chamber as well.

Thanks guys! ne particular heads ya'll recommend as a alternative to the gt40ps? I've seen the Jr heads (iron) and Sr heads around pretty cheap brand new assembled.....

While I've never had a set in my shop I hear some good things about the Patriot 185's and they are cheap.

Where did you hear good things about those heads at???? just about every fourm im apart of has a sticky about how bad those are.
