Description:

burnt a valve and seat pretty good in my AI 226cc 243 heads so looking to maybe buy a new set and fix these later... Looking to do something this week i hope, our tracks are open and I am missing out!

Looking for something along the TFS GenX or AFR 230 or PRC 227 lines.. Needs to be for small bore as i am running LS1 stroker...
Let me know what you have.. I am close to Nashville, Tn

Well, if you can be patient, I will have a set of fully ported 243's w/ .660 springs-TI retainers coming available. My machinist ported them w/ extra on the exhaust side. Make very good power, less than 15k on them, no boost/NOS and will be cheap for what they are. Base castings only had 60k on them. DM me, maybe we can make this happen faster. FYI, the 220's will work on your 3.90 bore no problem. It"s even the first head on their website when you look up LS1 applcations.
