I have a cylinder head question for you. I'm looking at a set of aluminum heads and they say they're set up for plus .100 valves and push rods. The valves and push rods I have are standard length, will this work or do i need to have the spring pads machined down .100?

valves are about 130 bucks a set of intakes and 130 for a set of exhaust.

pushrods, custom made, can be had for between 40 and 200 bucks.

dont scrimp on either.

I have new 2.02/1.60 RHS stainless valves and COMP Magnum pushrods planned on rebuilding a set of 487X heads, but came across the aluminum heads cheap but they are bare. Just need to know if they will work so I dont have to send all of this stuff back.

 

[Grumpy_old_fart]

who made the aluminum heads?

 

[1BMFK5]

Procomp out of Australia

 

[Grumpy_old_fart]

or is it china?

 

[1BMFK5]

Does that matter? Yes they are cheap heads I know but we've used a lot of their rods in dirt track motors with no problems, so i figured I'd give them a chance. We're talking a $100 difference in these or redoing a 40 year old set of iron heads

 

[Grumpy_old_fart]

cast iron aftermarket heads would be a better bet...

 

[1BMFK5]

They sure would at $700 a pair, but that's not what this is about.

check with a local,good rebuild shop. I just put the procomp heads on my motor,not the plus .100 ones just the regular ones. they look good. I got the valves from the same vender. I did get the bare heads and asembled them myself.I was in the same boat as you. get some iron heads and rebuild,or buy new irons or get the alu ones. I have $550 into mine. I have not ran it yet.

Listen to Grumpy: Get the proper valves and pushrods. The longer parts are needed to achieve the proper rocker geometry with your heads. Fuck with it at your own peril...

I should've bought a 5.3 :shaking:

 

[Renegade_◙╪╪╪◙]

If you can't figure this simple problem out you sure as hell don't want to get involved in a 5.3 swap.

I've done 4 LS swaps into A-bodies as well as a heads, cam, and intake builds on LS F-bodies including a 1391WHP T/A with a 22lb cog driven F1R 434ci LSX! I think I can handle it! :flipoff2:

yet you dont understand the importance of correct pushrod length...

yup, thats inspiring confidence...

Me thinks he's slightly embellishing his "experience"
