Head Suggestions for current L-48 setup?
Hey guys, so I am looking for some more power out of my L-48 which ran a best of 14.8s in the 1/4 mile and was thinking about heads but I am not sure what to get with my cam I have in now. My friend recently passed away and he was the one who helped install all of my current parts so I am in need of some extra guidance choosing mods. Here is the cam specs (http://www.summitracing.com/parts/CCA-CL12-211-2/), and intake manifold (http://www.summitracing.com/parts/EDL-37011/). Would vortec 64cc heads be a good option or would I have to get a different cam and manifold to match the heads?

Also would it be worthwhile to upgrade the carb to a holley 670cfm street avenger carb from the stock q jet? Other misc add ons I have include headers with dual exhausts, March pulleys and HEI distributor and I can't remember if we put roller rocker arms or not.

Stock vortec heads max out @ .450 lift and the intake is different. I would look at a Brodix IK 180, Dart SHP 180 or if your budget allows AFR 180 will get you more power. AFR 195 if your planning to upgrade to a bigger engine in the future. Go with a thin head gasket Felpro 1094 and any of the above aluminum heads. They will match your cam, intake and other upgrades fine.
Qjet carb is fine.

Take a look at these, they are the Dart SHP heads that Mako63 mentioned.

Thats a quick time! You have a 383? Iv thought about turning mine into a stroker but I am deciding to try heads first and see if they will improve my time along with a new dewitt's radiator to cool things down a little more and different tires. I would be happy to get in the low 14s high 13s with a L-48.
