no they have not been decked
patriot performance done the porting
im sorry i dont have on but badzracing is looking for it

 

They were not decked. They are stage 3 patriot heads ( cnc'd), but forcefed performance hand smoothed them and flowed them. I'm not having any luck locating the flow sheet at the moment, but I am still searching ( I moved and I know I have it, just gotta remember where the hell I put it). When I bought them new, I had them upgraded to REV valves, and titanium retainers to replace the patriot brand valves and steel retainers.

 

bumpity bump

 

consider trades on some worked 5.3 heads and some boot

 

Still have the springs or did they go with the heads?...what the specs on them? how much

 

not separating springs from heads

 

ok guys these are great for a big cube motor but my 5.0 will be drowned to beath with these high flowing heads help a brother out
