Is this a good trade
Is this a good trade I have a guy wanting to trade me a set of port&polished 853 heads for my prostars. They are 64cc cumbustion chambers. 2.02 intake, 1.56 exhaust valves. Patriot Extreme valve springs. idk flow numbers yet though.
These heads would be replacing my stock 241 heads. Would this be a nice upgrade or about the same, he says hes gonna put them up for 900 but would do a straight trade for my rims

depends on the porting, TSP sells the PRC heads, 5.3 stage 2.5 brand new for under 1200 and that is top notch porting with springs rated for .650 lift. Depends on what you want. If you do not have flow numbers for the heads you are stuck with his word.
Alrighty, asked him what the flow numbers were, and heres what he sent me back
Flow #'s are as follows: @.200 136
@.300 194
@.400 238
@ .500 270
@ .600 295
@ .700 277
These are the Intake Flow #'s
Exhaust Flow #'s: @ .200 108
@ .300 144
@ .400 174
@ .500 193
@ .600 207
@ .700 212
@.300 194
@.400 238

thats what im thinking, i mean he said he wanted $900 for them, but would do a straight trade for my rims. But if the heads are better then stock 241's then i would see it being to bad of a deal. Its just im not to smart on the flow numbers and such LOL
