LSupNorth6.0 Posted November 19, 2014 Report Share Posted November 19, 2014 Anyone running a set of PRC heads? Can I get your opinion on them? I'm thinking heads and intake next. PRC seems to have the best bang for buck ported 317's but I was also wondering about experiences with the PRC as-cast heads. I know AFR is legendary along with TEA, and possibly TF, but these are so expensive. I'm not going max effort, just more power for the $. I'm thinking of doing the stage 2.5 6.0 heads with shave to 68-69cc along with a port matched fast 102, NW 102 TB, and a 4" MAF. The as-cast heads unported flow more cfm than the stg 2.5, but cost about 350 more. Worth it? I have 1 3/4 headers, which I know 1 7/8 would be better at the point and I'm willing to swap. Like I said, think bang for buck please. Thanks in advance ! Quote Link to comment Share on other sites More sharing options...

12'SROCK Posted November 20, 2014 Report Share Posted November 20, 2014 You should get thw ls6 head so you can raise the comoression up and get better performance from them. Quote Link to comment Share on other sites More sharing options...
shawnss Posted November 20, 2014 Report Share Posted November 20, 2014 You should get thw ls6 head so you can raise the comoression up and get better performance from them.

LSupNorth6.0 Posted November 20, 2014 Author Report Share Posted November 20, 2014 Oh. Awesome to hear! I'm still kicking around whether I wanna toss boost on at some point, though I understand what your saying about the ls6 chambers helpin out. if i decide to go all motor ill prolly end up going with the PRC casting with the 65cc chambers. If you don't mind me askin, what cam are you running? Quote Link to comment Share on other sites More sharing options...
LSupNorth6.0 Posted November 20, 2014 Author Report Share Posted November 20, 2014 Id be pretty happy with 450rwhp NA... for right now. Lol. I have bigger injectors otw so I'm hopin to hit that mark by February/march when I have collected the rest of my parts. Well I checked out your profile and saw you have the 228.

12'SROCK Posted November 20, 2014 Report Share Posted November 20, 2014 Yea the ls6 heads are cathedral port heads. I have 60cc chambers. Quote Link to comment Share on other sites More sharing options...
shawnss Posted November 20, 2014 Report Share Posted November 20, 2014 Yea the ls6 heads are cathedral port heads. I have 60cc chambers. So what compression are you running? do you have a build thread. I'm going back in my SS with a LQ4 and I'd like to bring the compression up and do a cam. so if I don;t want to just mill my 317 to get my compression up I'm thinking of getting a set of heads.
