World sportsman heads

Found what seems to be a good deal for a set on my local Craigslist 64cc chambers 2.02/1.60 doesn't say but I assume they are 200cc fast burn waiting on an answer look clean in pics and price is right cheaper then the new vortec heads I was looking at. Anyone ran these on a mild 350. I planned on a vortec head lt4 hot cam 355

Re: World sportsman heads

A head with a 200cc intake port is a bit too big for a mild 355. A head with around 180cc's would be better.

X2, need at least 400 cubes for those heads.

World makes (or used to...) a head with smaller ports call a Torquer head, or something like that. would be good for a 350.

Re: World sportsman heads

Factory 5.3 heads run 200cc intake ports. Why everyone thinks its so big for a 350 is beyond me.
