My 430 block has a cylinder problem. The block is 40 over already. If fix the cylinder the 430 would become 60 over. I was told it would be thin an over heat..is the true? I have an option to fix the 430 block..or purchase a 455 block an do it 30 over which will make it 461. With the 430 heads and stage 1 valves which block shall I use? Mr.green
