No thinner than the oil land to 2nd ring land. Ruffly.080 Yes you can get a .035 or .062 copper head gasket. Ryker Racing sells the gaskets.

You want to turn your rpms to what the cam was made for. What billet cam do you have?
I would ask the builder when the power comes in and runs out. A cheetah grind maxes around 7500rpm some of Dynoís billet cams go to 9500rpm. If built right can turn the vanguard 10000+rpms on the track with heavier springs.
And they sound awesome at 9000+

Arc racing ,Ec disturbing , carrier performance have rods ,flywheels, cams, springs , retainers, billet cranks etc etc. parts on Ec are listed by cubic in. 28/31/33 and avs or non avs,
Your 19 hp should be a 33 cube avs, but I would double check your serial #.

Depending on how much valve to piston clearance you have. Using a cheeta cam or something less then 500 lift you could take off .045-.050 tho off more easy. Just puddy the piston when done to double check valve clearances. Wouldnít go less than .040 to piston.

400 trans will last a long time. I use 75/140w but you could just use 80/90. You can use both sides of output. Thereís a parts list on Here for all the bearings and washers, seals. Iíve never turned one on itís side , wonít last long as it wonít get oil to needle bearings on pinion shaft. I put a 1/8th pipe thread drain plug in bottom and a breather vent on top, then you good to go. Iíve put all kinds of rpm on trans never blew one up yet.

6Ē-12Ē wise rears will have faster acceleration out of corner and 15-16Ē rears will have more of a longer pull down straight. Bit more traction

Have you tried a new fuel pump? Where is your pump getting pulse from?

The 33 is a better head but you would have to cc 28/31/33 head to see if there is a difference in camber size

Use the aluminum ones. All you need to do is drill and tap stud holes to 8mm and file down tabs.
I got a couple sets of new in box newer style steel rockers you can have for cheap. Iíve bought a couple sets of new heads and they come with them, I use the aluminum ones and have never broke one.

First purchase should be a billet flywheel, then do your mods
