Product Details
When it's time to build a new engine or rebuild the heads, forget rebuilding your stock cast iron heads and buy a set of Patriot Performance Freedom Series reproduction cylinder heads. For the money you'll spend rebuilding stock heads you'll be miles ahead by buying Patriot's version of the stock cylinder heads. To start with they are aluminum which will save you 35 pounds, next they outflow the stock heads because they are CNC ported plus they are supplied with stainless steel 2.02" intake valves and 1.60" exhaust valves. And it gets better, Patriot heads have bronze valve guides which allow for tighter tolerances and longer life plus you get Viton rubber seals, new high lift springs, steel retainers and 3/8" studs and guide plates. So, as you can see, with Patriot heads you'll get more power for street and strip performance at a price that's tough to beat.
