Does anyone have any info on what his stage 1 package included? Not looking to start any arguments or critisize his work, just what this package would have included.
Thank you

 

I thought Jim retired. I do know he sold the Ohio shop, and moved to Florida. There are a few threads on a G body board about a semi-recent pair of heads that were not a good deal....

 

I had my Ga heads done nearly 10 years ago, so I have no idea what his current package includes.

 

Jim retired out of Iowa, to Florida.
He sold J&S to Tyler Jensen, who is in South Dakota. (605) 493-6465

You can try reaching out to Jim on Facebook (jlapikas)
He is not doing any machine work, to my knowledge
But maybe he can explain what was done on previous Stage 1 heads he prepared.

 

Thanks for the replies, I do not have facebook. The heads I have were done over a decade ago, I just dont know what was done with them, they are on a motor I have.

 

When Jim did the stage 1 on my heads they had larger valves, the exhaust cross over filled, the divider in the middle ports welded flush, valve job, and some porting work. Jim has always treated me well and my car with stage 1 heads ran 12.0 at 108 with a mild cam.

 

Thank you, I am more than happy with his work, engine runs great, I just wasnt certain what I had.

 

Well I got a question how big were the larger valves? Also hoping someone can tell me how big a intake valve can go without any problems? 2.10 2.12 and are these valves available of course I am talking for iron heads. 2.07 are in the E and C heads.

 

Go to Florida and ask him= road trip!
