TPiS Mini Ram Porting and 113 heads.
 

Doing a project for myself. '86 IROC with a '91 L98 engine. Decided to port the heads and use a mini ram. Converted the heads to 8mm 2.00/1.570 valves and used a LS drop in kit. Erson 226/234 camshaft. Should be a nice little fun ride!

Nice, did you get any b4/after numbers on any of it? I did a set of 113s almost 20yrs ago and we picked up 6/10ths in the 1/4 over the stock 87 350 iron heads.

Right off the car to the bench .100-.700 on 4.00 fixture
Reworked with 2.00/1.570 .100-.900 on same fixture
NO PIPE on either

Nice! I'm sure they will be fun! Is your portwork able to be purchased?

Re: TPiS Mini Ram Porting and 113 heads.

What is this LS drop in kit you speak of?

Re: TPiS Mini Ram Porting and 113 heads.
 

I use this kit in most of my LS stuff. All 8mm, seals, locks, locators, retainers (steel or titanium), polished dual springs.

I cut the factory .557 steel liner down to a .500 OD seal and used a Rapid 8mm guide liner.

How much does that texture on the intake side help? Never seen it before. You still post on the bullet?

Re: TPiS Mini Ram Porting and 113 heads.
 

Looking forward to seeing updates! Seems like this is going to be a pretty sweet little setup. Did you port to a 1205 gasket?

Re: TPiS Mini Ram Porting and 113 heads.
 

Yes, still mess around on the bullet.

texture is voodoo.. ;)

Chad, did you happen to get my PM?

Re: TPiS Mini Ram Porting and 113 heads.
 

Need some nice weather and a dyno. Also need a lift to finish the exhaust and put a new muffler on it.

Re: TPiS Mini Ram Porting and 113 heads.
 

That is one clean ride Chad.

Thanks! I have too much money in it, but it;s what I wanted! :)

How would these heads compare in cost and performance to a set of AFR heads, etc? I'm just curious.

Honestly, I wouldn't spend the money on them if I was a guy that was looking at heads. So much better stuff out there. I did it because I do this and I had them. If I did it all over I would put set of Pro-Filer or something like that on it. I still would have ported them. Just have a problem not touching something! lol

Re: TPiS Mini Ram Porting and 113 heads.
 

I ended up with about .570 lift at the retainer. Set of 1.60 Comp rockers.
