Hey guys. I am looking for a set of stock LT1 heads, bare or assembled, it doesn't matter, as long as they are useable and not cracked.

The other important thing is that I need casting number 10207643 or 10128374.

Thank you to anyone who responds.

My cell is 307 399 1696

Merry Christmas

Aren't you selling a set of stock heads?Anyways,I have a set of 374s that have been cncd 2.00 1.56 ferra valves,comp springs good for .650 lift,500 miles on these since being done.I will give you the flow numbers if your a serious buyer.

 

Yes I'm selling the lighter castings that are not ideal for porting to 200cc runner size. I need the 374 or 643 castings.

Question: Who did the porting and polishing on your 374's? What is the cc of the combustion chambers?

Thanks!

I have a set of stock 643's, clean, ready to bolt on, and assembled with brand new Comp 918 valvesprings. PM me if interested.
