Our client requested sleeves since he will be beating this engine HARD and they offered some extra security. (The engine was in good shape btw) We have had 100% success with CP Pistons and either Darton or LA Sleeve solutions, so its a no brainer.
Thank you Mike, I was just wondering cause i almost sleeved my block cause i wanted to push my car beyond the limits but with an aluminum block,i'm limited .
Whats involved in the stage 3 head,is it ported & polished cause the stock heads are state of the art.
What can you tell me more about the valve springs ?
Aftermarket or stocks I've seen are beehive design but these aren't ?
Good Luck with the build and great job guys
