Default alum. vette heads vs stock z28 heads

other than the obvious weight difference, what kinda flow difference are there between the two heads?? im looking for something to go w/ the lt4 hotcam, but dont need anything too radical just something that flows a little better...


would it be worth my time to get a set of Alum. vette heads of a 4bolt lt1 and swap them onto my motor??

LT1 F-bodies had aluminum heads as well. Only the B-bodies had the iron heads so i don't think Vette heads would do anything for you, unless maybe it was an LT4 vette.

If it's just the LT1 head then no, I wouldn't think so. They should be identical but someone will correct me if i'm wrong.

JAB...you're correct....there is NO difference between the vette lt1 and the camaro lt1...except for the 4 bolt mains....and the price tag.
most vette owners don't know that....they think they got something special

Im taking off my stock heads. Im going with a set of iron heads P&P'ed to the max with larger valves. Wanted Iron due to boosted motor. I was planning on selling old heads around $100 if you're interested. Im swapping them out around first of august.

i cant have any down time, pulling them off and sending them to le or even having it done locally will take a while, id rather just pick up a set. i dont need to, i can always use stock heads w/ the cam, just figured if some1 wanted to get rid of one for under 500 id take it.

Why don't you just buy the stock set for $100.00, send that in to LE and get LE1 or LE2 or whatever you want, have those installed, and sell the stock ones on your car now?

generally i don't have to tell them....most of the time they pull into the parking lot BEHIND me after they get the bright idea to play around....usuallly ends up in an severe beating for the vette....not many of them can hang with an 11 second street tire car...

chalk another one up for the f-body's against the plastic fantastics.

No. It was the exhaust. Otherwise the only difference is the mains.

The only cam difference in the Vettes and the F-bodies was the 92 Cam. It was different than the cams in the 93-97.

Then where did the Vette get the extra 25-35 extra HP? Couldnt be strictly exhaust change. I wish I could see dynos between the two stock for stock year for year.
