I am considering buying these ported heads for a stock bottom end 350 and 212/226 duration 515/555 lift 112 lsa cam. Im wondering if these numbers are going to produce the most amount of power in my top end WITHOUT significantly decreasing my bottom and midrange torque. Heads are 1075, let me know if you guys think they are worth it. Thanks for your help.

.100 71/62
.200 133/112
.300 187/157
.400 219/185
.500 248/192
.550 258.5/193.5

 

Looks perfect to me, but JMHO.

 

would like to see better #'s at .400 on the intake but the rest seem OK. The exhaust #'s seem VERY GOOD.

Some people have paid over $2000 for heads with these flow #'s. You will be happy considering the size of the cam that you mentioned.

Thanks guys for your repsonses, anyone else?

 

just realized the price on those heads.....WOW. I think you can get a better "deal" from Skarodom, he has more expensive heads but he can also do a "cheaper" set for about that amount with better #'s.

If those are local (no shipping, etc) it may be worth it but if yiou do not mind waiting or paying for shipping you can get a better set for the same (slightly less/more) $.

Do a search on porting or ported heads.
