Whats more cost effective? i think i have a 351w commin my way with "stock" heads on it... what option am i going to make the best power from:

A- Porting the stock heads
B- Buying aftermarket heads

and how much will it cost (approxmiatly) for either of the two?

i would go with aftermarket aluminum, porting the stock heavy cast iron will be better than stock but wont be as good as a good set of aluminum heads.
stock ported heads(cost cheaper) vs. lighter aluminum heads (more cash but worth it).........tough disicion.......
Find some used aftermarket aluminum heads how about that...lol

Get some used explorer GT40 heads and get them ported. They will still be cheaper than aluminum and will outflow the aluminum heads (if done properly.)

+1 Definitly do some iron heads... remember that Iron heads are able to withstand more abuse then aluminum heads

+2, my ported GT40P's came off a 10 second car. Wish I could have bought the whole setup [:@]

dont mean to sounds like a dick but why would you ask that go with aftermarket porting stock heads is a waste of money

Canfield Heads from Camshaft Innovations.
