Ok here goes...I was planning on using 318 valves in my soon to be modified slant head..but how do they have to be modified to be used
and what valve springs and valve retainers can I use with these valves??

Also Im in the market for a new harmonic balancer and heard a bb mopar
balancer will work on a slant but can I still use the stock pulley type setup
on it with a bb mopar balancer?? Im keeping the alternator on the car as it will still see "some" street duty... help!!

Small block (318) Mopar valves are to long for the SL6, it is better to yse the oversize valves offered by SI Valves or use big block Mopar exhaust valves as a starting point.

The big block damper will work but it is long and has no drive pulley.
Fischer makes a good SL6 damper.
