cold vavle set

I need to know what cold set for mechancial roller cam is,Block is iron heads are aluminum. i cannot recall what i s required all cam card has is the hot set

 

Motor is small block chevy hot valve set is .018 intake and .020 exhaust

 

Dart/aftermarket block, or standard? What heads?
But an average is going to be around 2 1/2 to 3 thou growth. So just subtract three from what you have and set them cold.

 

world products block and edelbrock victor jr. heads

 

I always deducted .005 for alum.heads with iron block. deduct another .005 with alum. block.

FIVE?!!! Holy crap! That is like big block numbers.
With a world block and vic heads, I say right at 2.8-3 thou. But one way to check is get them all perfect, then run a few after it sits for 10 minutes at full heat. Then you will know for sure. (each engine is a bit different.)

 

I usually go for about 2 thou on the inlets and 3 on the exhaust. It's an iron block with alloy heads.
