Yes, I've been getting lots of miles this spring. I'm almost 1500 miles this year with all the nice weather, even with a few setbacks in the engine.
I recently had to pull it down again due to a roller rocker going bad and eating up the end of the valve. Then the shop found that all the guides had been fitted too sloppy when new, and both heads would need all new guides. To compound things the guides used were imports and were too large at .509" OD, so more import guides would have to be fitted. I decided to cut my losses and traded the aluminum heads for a pair of completely updated old camel hump 2.02"/1.60" heads with SS valves, hardened seats, and CC'd chambers. Then I swapped the high rpm cam out for a smaller 272/272, .455" lift, 108 LSA cam. Also dumped the roller rockers and went back to stock 1.5 rockers.
The new cam and heads work much better! It pulls hard off idle to 6,000 rpm's, and has a ton of torque for a 327 Chevy. Very pleased with the setup, and glad to have it back together again!
