I've got a 350 out of a late 80's/early 90's Chevy Pickup that runs real good, but I am looking for a little more power. The heads I currently have on there have a casting #14102193. From what I understand, these heads aren't very good. Would replacing these with L98 heads make a noticable difference? Would a L98 or LT1 cam help out any? I'm on a very tight budget, so if anybody has any other inexpensive suggestions, I'd appreciate it.

well for the money the l31 vortec heads would be hard to beat.Also I would just call any of the major cam companys and let them know what you have and what your wanting to get out of a new cam.Flat tappets are much cheaper.

Aluminum L98 heads or iron?

What kind of induction system are you gonna use?

What's the engine going in to?

I was going to use a set of iron L98 heads. The motor is already in my '87 Formula and I'm still using the stock LG4 intake and carb.

As far as the LT1 cam with a carb,I don't know...
But I have an LT1 cam in my L98 TPI and it runs pretty good.
