new 360 advise needed please.

The heads, those 1.88 tulips are crap.
That needs to be addressed 1st, imo.

Throw some **** Master heads on it with a decent valve job done to them, then use a hydraulic roller in the 225* at .050 range in about 490/500. Lift...or if that's not cost efficient... go with a 223* .050 and around .490 lift.


Or save and use the 340 grind with some 1.6 and call it good.

I Like the small valve heads, if theyre 1.94 11/32 valves...but those 1.88 tulips are low,/mid lift flow killers. They suck...and something tells me you don't want to spend on some porting and valves.
The heads are most of the problem..that and the cam could be advanced some.
If you change to 1.94 and blend the bowls.. they'll pick up 20 cfm down low.
