Recently i've noticed a lot of you guys thinking of buying World Products Sportsman II Heads namely Mark!!! Well i found these https://asp1.secure-shopping.com/jrm...800000,2819000
for $679

:hail: :hail: :hail:


I can't say thanks enough.

Why does it say this though?

200cc Intake Runners
64cc Combustion chambers
Angle Plug
2.02 x 1.6 valves - Stainless Steel
For Racing Fuels Only


racing fuels only???


I just don't hope they all sell now , before I can buy them.

I need like another week.

AAH! Two days late.

Looks like I need to call Summit and see if they'll chop off another $50...

I'm betting they don't have harden seats installed to run pump gas.

Hmmm, how hard is it to change that?

I have been driving my car with the sportsman 2's everyday since fall and I havent had any troubles with them. They are the 64cc, angled plug, 2.02/1.6, 200cc.... so on and so on. I havent had any reliablility problems with the heads so far. Im not sure about the race fuel thing though. I never saw anything about race fuels when i was collecting info. You should be good to go, but get more replies and info before deciding.

p.s. just realize that these heads will grow with your motor (alot of potential), no matter how crazy of a setup you have. 500hp unported is ALOT of potential.

Funny, http://www.worldcastings.com/docs/catalog/pg10.pdf says they have hardened seats (exhaust, which is the issue w/unleaded). Doesn't say a thing about race fuel only.

Also says 450 hp unmodified out of the box.

Hmmm, thanks. Oh, think I could use the angle plug ones with Hooker headers?

i got angled plug sportsman 2's with my hooker long tubes and they clear better with the standard delco plugs than my old straight ones did with shorty plugs. i would venture to say that since they are emmissions legal that you can run pump gas with them (they even come with a sticker you can put under the hood stating they are smog legal)

very awesome heads by the way. all the features of the fast burn heads without the vortech manifold headache.
