Thoughts on Valve size?

Thanks for the input guys.
I intend to use the engine for a bit of low buck 1/4 mile use. Wail on it some, and see what breaks first. If I scatter it it's only a 318. 360's here are just too expensive.
Heads I have now already have 1.88's. And the zhorst valves are pretty sunk in.
I'll have to measure where the CR is down the track. I have cheap slugs with a 1.745 comp height. And .028 head gaskets. No-one likes a motor that's doughy down low. Horsepower sells cars, torque wins races.
I already have a set of brand new valves in the stock 360 size.

A bloke at an auto parts shop was telling me a while ago that he'd fitted 2.02's in his 318. I dont think he had it running yet though. Obviously I'll give it a home port job too.
