It’s going to take more than a little bowl work to get even close to 210(on my bench) from 302 heads.
That’s about what a medium to poorer flowing OE 2.02 J head flows.
I’ve had the current bench for 11 years....... and in that time I’ve never flow tested any “318” heads.
Going from memory, I seem to recall them flowing in the 175-180 range on my old bench.
I think the best of the 1.88 valve heads are the 308’s, which are a bit over [email protected] lift with a decent valve job on the current bench.
