Thinking about GT40Y heads, would I notice a difference vs GT40P?

I currently have stock gt40p heads and was more than likely going to GT40y aluminum heads.

Would there be fairly decent improvement? I would saving 50 lbs alone just by going to aluminum.

I would also be installing a trickflow stage 1 cam and 1.6 roller rockers at the same time.

i have the y-heads on mine, just got them ported and a valve job done to them, they are definitely flowing alot better than they did before, i would get some edelbrocks or something that flows better right out of the box and then theres always room for more improvement later. unless your getting a good deal on them, your not gonna feel a big difference at the track or on the street by putting them on out of the box.....gotta figure y heads have been around for quite a while now, alot better heads have come out for around the same price, just my opinion

Performance wise in stock condition, they are almost identical.

I decided not to go with them after all.

Thanks for the input.
