You may need different valve springs or different ratio rocker arms. But I dunno about complete heads. I have a decent size cam with stock 1.94 heads and different valve springs and rockers.
The size of the valve doesn't have as much importance as the actual flow rate/capacity of the runners themselves. You need heads that have runners capable of flowing the air needed for you camshaft choice. Springs will also become an issue with a larger camshaft because they have a limit as far as how far they can be depressed and then return properly :idea:
Having an engine that is bored .030" over does nothing to the heads :|
What size camshaft are you looking to get :?:
What heads do you currently have :?:
What intake manifold :?:
What carburetor :?:
Do you already have headers and a higher stall speed torque converter :?:

The general rule is not to go over .480" lift with a factory cylinder head :idea: The more "performance" factory cylinder heads will be able to properly flow a camshaft up to the .480" lift range
Hope this helps

The worst thing you can do is "Over" cam an engine. There is no point in a big cam if you dont have head to match. Lingenfelter always said he would rather put on a good set of heads rather then just putting in a big cam.
im not sure the what heads i have i never took my motor apart ...i have a edlebrock performer intake and how do i tell what size the carb is??
the carb is edelbrock and has the numbers 1406 2380 ..is this a good carb? it came on the motor when i bought it..
A very simple way to identify your heads is to pop a valve cover off and get the casting number from the heads. This will give you an idea of what you can realistically run for a camshaft with those heads.
