Years ago when the Intake gasket let go at 90M I added a Cloyes dbl roller and new cam/lifters in my '83, and at 325M still no issue, and pops right off. But Rollmaster CS7041 timing set is the best. Otherwise go with Cloyes True Double Roller 9-3513X9.

Awesome, thanks for all the advice. My objective is to keep it stock and reliable. The previous owner, a friend who never drove it, babied this car in storage. I got it after he passed and I am using it on many long drives as I can, at least as long as the 307 stays together.

Went with Cloyes the last two cam wheel changes I've done. The most important part of the swap is the steel gear for the cam. You will likely find that the crank gear is broached for multiple timing settings, retarded, straight up, and advanced, by so many degrees, for each location. It is a magazine article on how timing changes at the crank will affect torque vs horsepower and YooHoo-Tube is your friend in that respect. Double roller, even if only on the street. There are some nice components coming across the pond from The Aussies and even Taiwan generates some strong sturdy bits. This is not like the old days where certain countries used to be synonymous with mediocrity. They did learn from their mistakes and got far better in the process. I would personally take a Taiwanese made part over a mainland Beijing built piece of useless dreck any time; just saying.

The only knocking 307's I saw or heard of, other than one blown up 85 swirl port motor from a Buick Wagon were from 83 H/O 307's. The gearing and close to 5000 rpm shifts are pushing the 307's comfort zone. Being babied and well taken care no doubt helps. I would run 10W40 which I believe is the factory recomend oil.
