The engine is a roller cam engine pulled from an 89 formula. Stock cam. I've done some searching and come up with 7.200 being the correct pushrod length. Checked jegs and came up with this

I just want to make sure this is correct since that's actually cheaper than stock.


Also, I'm doing a head swap next weekend going from the stock L98 head(64cc?) to a 67cc World S/R head. What size head gasket would be best used here?

 

Best idea would be to do the felt tip marker job on the valve stem with an adjustable measuring push rod. Then you're sure of the length.

 

I'm getting confused on finding the stock pushrod length. Everything I'm reading here is saying 7.200 but all parts stores in my area sell 7.192.
