Heads specs ??
Heads specs ?? Currently in the process of a rebuild. It's an LT1, I already posted in the LT1-LT4 forum, but have gotten no results...so I am trying here. We are building a forged 383 stroker. Last motor had the "306" cam, .230/.244, .540/.560lift, 112LSA. Looking to going to a bigger cam with the rebuild. The heads are stock LT1 heads that have been ported out to the numbers below. I have no idea what these numbers mean. My question is for anybody who does know....Will these heads work well with a rebuild, or should we get some new ones from AFR? Is there not enough information given to answer that question as well, and if I was to give these numbers to Comp Cams, could they come up with a good grind for these heads. Thanks guys.
