Does anyone know if 7/16 pushrods fit Trick Flow 240 heads on an RB Block? If not, how much clearancing is needed?
I'd like to use straight PRs if possible (I'd like to avoid taper or double due to cost reasons).

Thanks

I used 7/16 pushrods with the Trick Flow heads on my dry sump 470. I had to clearance the pushrod holes. It didn't require a lot of work but you need to have the correct setup. A rollover fixture in a milling machine works the best and then you need a long mill to reach down in there.

Good thing is that my dad has a milling machine with a rollover table. Did you clearance the pushrod hole all around or just on one side?
