Closed chambers gone bad… that’s a wrap
Unfortunately pistons kissed the the 65cc SM heads luckily not enough to damage the heads.
These were the old speed pro high compression 340 style poking out the deck, ran the stock .053 head gaskets but just wasn’t enough. At this point I’m thinking of just having the lower end redone, going stroker route and starting fresh using the heads and 1.6 rockers I bought.
Luckily piston walls are good no scoring from what I was able to see but certainly will have it checked. Been a great learning curve not the outcome I was going for but **** happens.
