Keep your head, and have DPR take care of it. You will be very happy. Dan does great work!

I agree keep the GSR head. Alaniz tech also does great work. Their competition head jobs are sexy as all get out.

 

hmmm sounds good.... thanks

 

Keep the GSR.... I like that head better anyways... If you aren't doing any bottom end work then it will keep your C/R stock unlike the PR3 cast and the P72 ported still flows better on top end than a PR3 it just doesn't make the midrange... Always gotta recommend Tom at Portflow, he does awesome work... Just my $0.02... Latez

 

well your starting out with a good foundation, the GSR head I have found makes really good power, I don't reccomend you use skunk valves they are made from a really cheap material, I would use either a REV valve for a NA app.or a ferrea valve for turbo app.
