Heads..
 

I have the Low end torque type swirl port heads, and i get 25mpg city and highway mixed... however i dont want to kill that, just want to boost my Horsepower/torque Up near 5000rpm..

shave em. or cheaper yet, put a really thin head gasket in.

or get a pair of 416's or w/e ther are...

fast burn heads. not 416's thats an upgrade for 305's but idk about 350's

I'll find something over the winter while the car is parked. and I'll hopefully have built up some Money, for heads, and New rear end..

How is this a product review?
