I have two sets of heads and dont know which to go with. ITs a comp 292 cam with all the bolt ons.

1. Stock Gasket ported heads with a 3 angle valve job, stock size valves.

2. 2.02 /1.60 camel hump heads. Valve job.

Which should I slap on?

 

whats the casting numbers of the stock heads?

 

I'd go for option # 3... sell both sets of heads and put that money towards a good set of aftermarket heads.

Seriously, when that big cam (244* @ .050 ! ) starts coming into it's peak, the heads will be signing off. So you lose low end torque with the big cam, with no return to show for it upstairs. Either one of those heads is taxed with any cam past ~ 224* @ .050".

 

where is the casting number located? Is it the one that starts 333 bla blah blah? Would I be better off with a smaller cam?

If you are going to use factory heads, you're probably better off with a cam in the 218-224* duration @ .050 range. JMO
