is it worth 450 to port and polish stock heads?... and is it worth 180 for a valve job?

 

for those prices not really. on this site u shouldnt give advice if u dont have experience but with this one i do, ported stock heads will work well with other mods, if u put a pretty decent sized cam and intake to match u will c a big gain in hp, but not for those prices, I would search around more or find someone who knows how to do it on the side for cheaper.

 

just pick up a set og gt40s for that money they will flow the same and they will nto even be ported

 

yeah thats not even worth it go to the junk yard and get a set of gt40s for like 150 bucks

 

just go to the junkyard and get some gt40s like everyone is saying and than port them out, u will c a lot more hp that way.

 

i doubt any junkyards around here have them ive gone to alot of them and i never find what im looking for... how much should porting and polishing cost

 

You should be able to find a decent set of used performance heads for that much money if you look around.

I really wouldnt put that much into stock iron heads.
