So, heading down the road this weekend and spit out a spark plug. When I limped it home (loudly) I realized the spark plug had been previously repaired. Time sert blew out with the plug. I had thought about using an oversized timesert but considering the kit is as much as a head, that seems like a waste of money on a fix that might also fail.*
Decided to do new heads. I have a 1915 with a scat 35 cam, center mounted weber 32/36 progressiv. My original heads were 040 s with a port and polish job. Performance was ok.
Have been looking around at heads. Thought about the mofoco pro street 040 (699 a pair) or possibly moving to a pair with larger valves like the 40/35.5 combination. A few of these on ebay, but not name brand so im not sure about those. Any suggestions?
