I have a 2 bolt 350 that I've been building for 2 years and I want more power. I know I need to get some vortec heads. I have stock heads with comp cam Thumpr (CL-12-600-4 Hydraulic Flat Tappet Cam and Lifter Kits), I'm not racing or anything its just a cruiser and something to put in some car shows.

My question is do I continue to go the route I'm going with the vortec heads or go another route??

I have an 1987 MC SS

 

vortec heads on a 2 bolt 350 can easily make 400 horsepower,consider a better cam though not just noise maker.a roller cam would be ideal and make more power efficiently
