I like the Speed Master Cylinder Head suggestion allot. It is a baseline upgrade option besides magnums, rare W2's (good luck finding afffordable rockers), rare RHS's, and the latest out of production heads: Engine Quests.
W2’s aren’t rare.
Affordable is in the eyes of the builder and their pockets.
It’s also a more expensive rocker set than a standard LA but it’s as normal, lay more for better. While the rockers themselves could be made by the same company, they also charge more for off set rockers and units not often made. Often made rockers are cheap. AKA Chevy as an example.
Looking at it another way, do a price comparison.
Go to summit and look up Harland Sharp rockers for the LA and W2. A small increase in price for a far superior off set rocker no pinch rod problem head.
