Good morning all! I have a 1975 L65 350 with a stock bottom end. Mods to date: -mid length headers & 2.25" dual exhaust -aluminum dual plane intake -4bbl Q-jet -bumped up timing -HEI distributor re-curve Until I can afford a cam & head swap, I'm considering swaping out the factory stamped 1.5 rockers for 1.6 rollers for a little extra valve lift, has anyone done this? My concerns are (given the following factory specs: stock cam with 0.300/0.307 int/exh lobe lift & stock 882 heads with 1.5 ratio stamped rocker arms, therefore 0.45/0.46 ink/exh): a) will the stock 882 heads handle the extra lift with 1.6 rockers (0.48/0.49 int/exh)? b) will piston to valve clearance be an issue with the extra lift This is a weekend street machine & I'm just looking for a little extra giddy-up! Any advise/experience would be much appreciated. Maybe I should do a little home porting/port maching???
