GPI Ported and Polished Heads
Finally got a set of GPI (Gwatney Performance Innovation) Ported and Polished LT1 Cylinder Heads. Beautiful pieces of workmanship, I must say. We kept the chambers stock and we milled a good amount to bump compression. The E85 should love the little bump in compression.
I am adding these along with finally installing my Circle D 4C converter and hope for 10.6/10.5 ET within the next couple months! All while still utilizing the STOCK camshaft! Went 10.90 @ 126MPH last week in about 1000DA and 80% Humidity. My PB of 10.87 @126mph was in Negative DA and 30% Humidity. If you want good quality track proven products and great customer service, hit up Ryan (Rhino79) or Aaron at GPI (https://gwatneyperformance.com)!!

Thats a lot of work not to swap cams. Are you doing the work yourself?

Not really. You can do a head swap in a day if you know what you are doing. I would almost consider doing heads a "bolt on". Doing a converter takes longer and is more involved than doing the heads on this car. A cam swap is no joke and takes two to three times longer. It's not like the old days.
