Thankx. good info any opinions on domes vs angle milling on W5s



W5's have a VERY thin deck so dome pistons are THE right choice. If they had thicker decks then angle milling would defintely add potential power.

I'm sure when Ryan does the W5's he replaces the guides with 11/32 or at least installs liners to drop the stem size down.
Lately we've been dropping stem sizes down on Indy stuff to .312 with good results. Lightens up the valve train a bit.
