I've been looking all over for a while now and can't find any flow charts for the GM performance head. i am debating between either that, Mr2 or an Ammfab ported head. I pm'd Ammfab yesterday, still waiting on a reply though. I want nice flow and just wondering how it compares to the other 2.
patriot makes a really good head... i believe pj was running that head with level zero cams and it ran really well... im not totally sure so dont quote me but i know the patriot heads are a great deal.
from what i've read, the patriot really isn't ported much. I'd rather have a p&p done for 1/3 the price locally for a mild port. for that price i'm looking for heads that have high amounts of flow.
