Heads only for LT1
If I were to have my heads reworked for my 93A4 what kind of power increase could I get while running the stock cam ? I like the Factory exhaust and the smooth idle but I also want more power. I am running a 2800 stahl and a 3.75 rear and wondering if a set of heads only could pick up 30-40 rwhp or am I dreaming. I took the hoodstripes and hashmarks off my car and ditched the flowmaster exhaust as well.
I am hoping with a 100 shot and a set of heads I could have one hell of a sleeper with the bottle in the spare tire area. Thoughts ??

with the stock cam i think that much of a rwhp gain is a bit optimistic.if you are going that route i would have the porter concentrate on the low and mid lift flow numbers.a large percentage of any increase will come from there.with some 1.6 rockers and a good porting(i would want a baseline flow bench and one after on the same bench)i would guess 25rwhp is attainable.the hotcam is mild enough and some more hp to that.do it once and save the headache later.you already have the gears and stall for it.

If I can pick up a good power gain while keeping it sounding and looking STOCK I am all for it. So what are the choices here guys ?
Buy a set already done, have mine reworked, a set of aftermarket heads ??

I think the caprice heads are steel. I am not up on who has the best heads for an LT1. I would guess afr. I made the mistake of pumping a ton of money into a stock set of 113 castings. They worked well, but I spent too much money for minimal gain.

how much are you looking to spend? afr is great but they do cost. lookin into lloyd elliot, does an excellent job on porting stock castings.. also i would step right up to the hotcam atleast, and you can always keep it.. sleeper? its a corvette so i dont know how much sleeper means haha.
